A Galaxy Far, Far Away — first few days with a Samsung Tablet

I’ve spent the past couple of days with a T-Mobile variant of the new Samsung Galaxy Tablet. To cut right to it, I’m pretty impressed.

The key with this device, like the iPad and the super-sized Smartphones that are coming out now, is what you intend to use it for. And for me, it has a lot of promise. The phrase “for me” occurs a lot in this post because that really is the critical point. The Galaxy has had some very mixed reviews, and frankly it reminds me of the negative reviews many netbooks get. This is not a desktop/laptop replacement, but for certain use cases, it works very very well.

My primary phone is trusty Nexus One. I’m all-cloud these days, so Google has my contacts, email etc, and Google Maps has replaced whatever little sense of direction I had. As a phone, it’s great. As a “mobile companion” to keep me organized, also great. I don’t play much music on it, but it’s an okay media player (although better at photos and video). And yes, it’s nice to have a pocket device that runs flash.

But there are some issues. Battery life is a constant concern. Emails are generally kept short and I don’t author documents. Just too much like hard work.

And for me, that’s where the Samsung shines. As a portable “more than a phone, less than a laptop” device. Yes, I know that’s what the iPad is supposed to be. But for me, the iPad is a little on the large size. The Samsung isn’t pocket sized (unless you have ungodly big pockets), but it is pretty light and small compared to the iPad. I wouldn’t leave the iPad in the car unless I put it in the trunk, but the Galaxy is small enough to fit in a glove compartment or side pocket. It also weighs less than a pound, so it is much more like carrying a notepad (yes, a paper one).

Aesthetically there’s not much to say. It’s a black rectangle with rounded corners. Yay. 7” screen, front and rear facing cameras (but no Skype support for video calls yet), stupid Apple-esque connector, and volume/power buttons. It’s also running Samsung’s Android UI, which is a bit of a mixed bag, but overall has some nice touches. The device runs Android 2.2, supports Flash out of the box and has built in 3G.

The Android status tray has been modified to include easy switches for Wi-Fi, Bluetooth, GPS, Silent mode and Orientation lock. The latter is especially handy as you don’t need to fumble around for a physical switch to lock the device in portrait or landscape. There’s also a brightness control, although the auto mode does a decent job.

The screen is very bright and clear. Good color and decent readability under most lighting conditions.

But back to what I use it for… Yesterday I was on a 4 hour flight that happened to have in-flight wi-fi. I was able to take care of a bunch of emails, send some urgent SMSs via Google Voice, author a couple of Word docs, sketch out a Powerpoint, remote log in to my webhosting company and set up a test Drupal server (not a fan, but that’s another post), all while listening to music.

The flight was packed full and the guy next to me was trying to do the duck-typing thing on his laptop (elbows in, repetitive strain injury at the ready). Before his Thinkpad had even finished booting, I was already finishing some tasks. When we had to put our toys away, I still had 60%+ of battery left.

Apps are generally responsive. I haven’t had many issues with the browser. My only app-related issue is how much pre-installed junk is on the device. I really wish manufacturers wouldn’t do this. Or at least let me uninstall the cr*p I really don’t want. It seems the good old days of Desktop Bloatware are back with a vengeance.

There are some rough edges. The auto-correct doesn’t always recognize password fields, which can make typing in passwords a nightmare. Not to mention that your password appears big and bold in the suggested word panel as you type. There aren’t many good tablet apps yet, although some apps already look good (like Angry Birds). We really need an equivalent of Mujinote for this device. Also, with such a big screen, the text size is simply way too big in many apps. For example, in Gmail, you can shrink the size of the message text, but not the list of messages in your inbox. You could fit a lot more readable stuff on the screen if the font size was smaller.

I also really wish Samsung hadn’t gone the Apple route of proprietary flimsy connector and sealed battery. I don’t care about replacing the battery, but I do care about recovering from a completely locked up device. The latter hasn’t happened yet, but I’m not sure how you recover if it does.

But all in all, for me, it’s a handy device that means I take my laptop to even fewer places, and that’s a win in my book.

Can you make F**k You Money at Radioshack?

NickN| October 5, 2010 7:02 am

Vivek Wadhwa is exactly the kind of academic I would expect to be well meaning but disconnected from reality. He’s clearly very very smart, a visiting scholar at UC Berkeley, as well as a Senior Research Associate at Harvard Law School and a Director of Research at Duke University. But the reality is that this guy knows his stuff. His research is insightful, applicable and I really wish more policy makers paid attention to what he said.

While I enjoyed his direct (and very accurate) description of RTP and its shortcomings, the more thought provoking article was a discussion on Techcrunch about entrepreneurial exits. He digs in to whether entrepreneurs should be chasing billion dollar exits or cash out “small” with a paltry $50MM exit or so.

For those of you who are unfamiliar with the world of Venture Capital, the quick summary is that a small exit doesn’t really work for traditional VC investors. They have to push for a big exit to offset losses from the investments that fail.

One part of the article particularly caught my attention:

“If you’re a founder and own 50% of your startup, a $30 million acquisition can be life-changing. With a $15 million payout, you go from poverty to riches. You’re set for life: you can afford to send the kids to the best schools, buy a multi-million dollar house on the hills, live a great lifestyle, and personally fund your next startup (or you can become a “super angel”). The difference to you between $15 million and $150 million (if you go for the billion-dollar exit) is small—the extra millions really won’t change your world that much more.

I imagine that quite a few people find that absurd. How can $150MM not be dramatically more life changing than $15MM?

The answer stems from the many levels of what is most easily called F**K You Money (FYM).

FYM is shorthand for a lot of things. It implies being able to buy what you want, when you want, living the lifestyle you want and doing as you please. It’s a goal of many entrepreneurs, at least in terms of the perceived freedom it brings. But what qualifies as FYM is very dependent on circumstances, and that is definitely something worth thinking about.

My first brush with FYM was when I was 17 or so and was headhunted to work at Radioshack. Okay, headhunted is a little strong. I had a buddy who worked there who was leaving. His boss had met me a couple of times, asked for an intro and offered me the job on the spot. For a kid in High School, Radioshack was the big time. They paid more than any other nerd-oriented retail outlet for part time staff. As I recall I was making $4 or $5 an hour. Within a few months I had banked a few thousand dollars. I bought a bunch of music gear (including something similar to one of these) and had enough money left over to fund my first year beer tab at University. I had FYM and it was good.

Now of course, when you are 17, your expenses are pretty low (thanks Mum & Dad) and so are your expectations for what constitutes living the proverbial high life. But to this day, I’m not sure I’ve ever felt I had as much disposable income as I seemed to have back then.

My second brush with FYM happened when a company I worked for was sold. I was a senior executive, owned a tiny bit of the company and got a payout. It certainly wasn’t a million dollar payout (not even close), but for a young-ish single guy, it was a good chunk of change. It was also a couple of hundred times more money than my previous FYM experience. I had no debt, a shiny new car and was paying almost no rent. I could eat out any time I liked and there was always a large amount of my paycheck left over at the end of the month. I went to a four star hotel in Hawaii for a couple of weeks just because I could. Life was good.

Now that I have kids, debt and a generally more complicated life (not a complaint – I wouldn’t give up being a husband to my awesome wife or a Dad to my kids for any amount of money), the threshold for FYM is a whole lot higher. I’m guessing it would need to be 20-30 times higher than my previous FYM experience to be sustainable.

And that’s exactly what Vivek was getting at.

If you made $15MM from the sale of your company, you could buy a nice house for cash, get a pretty nice car, pay off all your debts and live comfortably off the interest from fairly low-risk investments.

Compared to life before $15MM, this will be a radically different experience. If your lifestyle is based on a more or less normal salary and more or less normal level of expenses, a whole new world will open up. Sounds like FYM to me.

But what if you went from normal to $150MM? Well, expenses always manage to somehow stay in line with available income. So you’d probably buy an even bigger house, maybe get a splendid but silly car or two and so on. But your life would not be materially different from the $15MM scenario.

Now consider a third case. Imagine you’re already in the $15MM lifestyle bracket. Does a $15MM exit make a material difference in your life? Probably not. If your expenses have expanded to fill the $15MM lifestyle, you’ll need a 10x bump to see a significant difference.

At the end of the day, I suppose it is really very similar to company revenue versus size. If you are a startup with revenues of $2-3MM, a $15MM deal is huge. If you’re a $150MM company, $15MM is nice, but not world changing. If you’re a $1B company, $15MM is almost irrelevant. It’s all about moving that corporate needle.

So when you’re daydreaming of your fantastic entrepreneurial exit and joining the cult of FYM, remember that just enough is often more than enough. And enjoy it when you get there…

Adios AT&T – Adventures in jailbreaking an iPhone 3GS

NickN| August 7, 2010 12:49 am

I’m temporarily very very technologically happy… And it’s mostly because I can put AT&T behind me. Adios AT&T aka Awful Telephone & Technology co. Hello T-Mobile.

I’ve been itching to make the switch for a while, but my better half uses an iPhone and the jailbreaking thing has always seemed rather convoluted.

First things first, for those that don’t know…

Jailbreaking is the process of eliminating Apple’s almighty control over your iPhone. Once jailbroken, you can make all kinds of changes that Apple won’t allow and install all kinds of applications Apple won’t approve.

Carrier Unlock is the process of eliminating AT&T’s unholy grip on your iPhone. Once unlocked, it will run on any GSM-based network. In the US, that means T-Mobile. If you ever travel abroad, it means more or less any carrier in the world except parts of China.

Simply put, you cannot do a Carrier Unlock unless the iPhone has been jailbroken.

Fair enough. Oh, and I’m going to say upfront:

a) Back up your iPhone before you try this
b) Be afraid as things can go wrong
c) Be patient for the same reason
d) If you’re not up for google-whacking to get answers, don’t try this at home

and last but not least:

no, I can’t help you if you get stuck!

Anyway, on with the fun. The model I’m working with is a late model iPhone 3GS. The phrase “late model” is key. When you look at the Serial Number (listed under Settings -> General -> About) you’ll see it starts with 5 digits followed by a letter. The last two digits before the letter are the week of manufacture. If it is a number bigger than about 40 (opinion varies slightly) it is a late model device. The bad news is that jailbreaking a late model device can be messy as Apple changed the device’s firmware in an attempt to thwart the hackers.

My first successful jailbreak was using blackra1n (ooh, sounds very Hackers, doesn’t it). This is a simple enough app — you download it to your Mac/PC, plug in your iPhone and run the app. The phone reboots to a rather un-Appley boot screen and seconds later you’re jailbroken.

There is however, a caveat. If you have a late model device, you end up with what is called a “tethered jailbreak”. This is cunning hacker-eze for “not the dream you were looking for”. If you ever have to reboot your iPhone, it has to be connected to a computer with Blackra!n in order to boot. If your battery dies, or the phone crashes, and you don’t have a laptop/desktop handy, you’re stuck without a phone.

However, Blackra1n does install Cydia, which is rather handy. Imagine Steve Jobs has a stoner/hacker/anti-the-man brother (or sister) that creates their own version of the iTunes app store, and you have a good idea of what Cydia is. It contains all kinds of useful goodies that can be installed, from settings to carrier unlocks to applications Apple won’t approve.

So after a tethered boot, I fired up Cydia and installed Ultrasn0w, which is a carrier unlock from the infamous DEV-TEAM (the folks behind much of the iPhone hackery that goes on).

Once you’ve done that, you’re free as a bird. Grab a paper clip and stick it in the tiny hole next to the headphone jack to pop out your old SIM card (a tiny card with a chip about half the size of a stamp that tells the network what your number is) and drop in the new one. You’re now free from AT&T!

Well, almost.

You need to set up some network settings for data access, switch on data roaming and then set up your MMS settings if you want to send photos with texts. T-Mobile are pretty helpful over the phone, but the MMS stuff is a bit tricky. More on that in a minute.

So everything more or less worked, but the jailbreak was tethered. And sure enough a couple of times the phone ran out of battery and had to be re-connected to my laptop.

So ever the adventurer with a fondness for technological screwups, I decided to try something new. I restored the iPhone 3GS to its original state and then updated to the shiny new OS 4.0.1 from Apple.

Since I had backed everything up first (you did do that, right?), restoring all of my apps and photos was easy. Just hit the Sync button in iTunes and leave the phone alone for a while.

Minor bump in the road: when you do a full restore, the phone needs to be activated. This REQUIRES an AT&T SIM card and AT&T service. Fortunately I haven’t shut mine off yet, so a quick SIM swap and a reboot and all was well.

Probably best to switch on wi-fi and connect to a network at this point.

The next step relies on a rather nasty security bug discovered in Adobe’s PDF file format. I won’t bore you with the details, but by simply visiting a website you can Jailbreak your iPhone running iOS 4. Again, the website is http://www.jailbreakme.com.

Just fire up Safari on your iPhone and go to the Jailbreakme.com site. Slide the button and it will start the process. It was all very easy and only took a few minutes to complete.

Better still, it is an untethered jailbreak. No more rushing for the laptop after a reboot.

The jailbreak installed Cydia, so once it had completed, I simply downloaded the Ultrasn0w package again and swapped SIM cards. Happily unlocked and running on T-Mobile.

But you’re not done yet. Two things left to do.

  1. Fix data access to T-Mobile’s network
  2. Set up MMS

The data access stuff is easy. Go to Settings -> General -> Network and switch on Data Roaming. Then select Cellular Data Network and next to where it says APN type in epc.tmobile.com. That’s all you need to do.

Bear in mind that you will not be able to get 3G speeds on T-Mobile. They use a different frequency to AT&T so it simply won’t work.

Now MMS is a bit tricky and I had to try a bunch of things to make it work. I’m not sure if all of these steps are necessary or not… I was able to pretty quickly get the iPhone to send MMS messages, but every time it tried to receive a message, it produced an error stating that the media content wasn’t included and implying that the incoming file was too big.

The combination that seemed to work for me was as follows.

Go here:

http://modmyi.com/forums/t-mobile/656651-t-mobile-usa-carrier-bundles-bluetooth-internet-mms-tethering-2g-3g-3gs-4-a.html

Scroll down until you see the following link:

DOWNLOAD T-Mobile US iOS4 1.1.1 IPCC

Click the link, download the zip file and unzip it. In the list of unzipped files, you’ll see a README.txt file. Read this carefully. I installed the ipcc file for T-Mobile Prepaid.

After doing everything the README says and rebooting, I could send MMS without a problem, but receiving was still broken.

The last step is to go here:

http://modmyi.com/forums/general/719997-media-content-not-included-help.html#post5353764

and read post #3.

Fire up Cydia on your iPhone, select Manage -> Sources -> Edit -> Add and type in:

htttp://beta.leimobile.com/repo

Then hit Done and select the LEIMobile Repo from the list. Scroll down until you see T-Mobile 4.0 MMS Fix, select it and install it.

One more reboot and you are done.

It’s not for the faint-hearted, but freedom from AT&T is a beautiful thing…

P.s. Please note that the security hole that Jailbreakme.com uses is a doozy. I cannot imagine it will be very long before Apple updates iOS to block it as it is a very real security risk. But I’m equally sure that the crafty hackers will figure out a way to break whatever they come up with.

Lazy Blogger Syndrome…

We’re now in the 3rd month of 2010 and I’ve yet to write a blog post this year.

Actually, I’ve not written anything this decade.

Hmm. Maybe that will guilt my subconscious blog writing ego into action. Stay tuned…
