Poof. Phone gone. 'twas a real pro. I carry my iphone in a case with a very difficult to remove clip attached to the inside of the front strap of my computer bag, which I always hang diagonally across my chest to make it more difficult for someone to run off with my stuff. Doing this places the iphone in its case between my chest and a somewhat tensioned strap. During the afternoon on Thursday, I vaguely registered that I was bumped into a couple of times while walking through the WTC "Viewing Area." I'm accustomed to this as navigating through there without screaming at slow-moving Midwesterners (of which I was once one, so I try to be nice) sometimes proves difficult. I don't think I'll be taking my subway shortcut any more.

If you're wondering what's the absolute worst part about getting an iPhone stolen, it's not that creepy feeling of violation that comes from having one's personal property lifted, it's transferring service to a new iPhone through AT&T. I had originally opted to avoid the two-year AT&T suck customer service lock-in with a "Go Phone" plan, gambling that somebody would come out with a hack that would allow me to use (say) T-Mobile with my iPhone. Until that happens, though I would just love to be able to use the device in the same way I have been. When I got my new iPhone, I thought perhaps the option to transfer my current AT&T number to a new phone would be the logical one to choose. Nope. Apparently, AT&T/Apple never thought that anyone would want to transfer service from one iPhone to another (at least not on the "Go Phone" plan). Long story short: as of right now I'm out the 78(ish) dollar balance I had in my "Go Phone" prepaid account as well as a new activation fee. Why? The only way I could get an activation (according to AT&T customer service) is to go through the "I want a new contract" activation process (without the "all nines" hack). Since my credit doesn't suck, I have a two - year AT&T contract to try to get out of now. That is a pickpocketing I'm going to fight.

For those waiting for iPong, I was expecting to have it ready for public consumption by tonight, but have just jailbroken my new phone. The network error handling and preference code was coming together nicely before my little adventure. I should be able to release something fairly stable during the week.

The way-too-adventurous among us can find the code as it stands now on google. I moved the repository there a few nights ago in anticipation of the release.

Sent in an email recently.

Carburetor tuning:

Even when you're doing it right, anything you change in one system will often screw something up in another unexpectedly.

Sometimes starting over from a reasonable baseline is better than hammering away at a not-quite-right but oh-so-close-to-working plan.

Keeping track of what you've done makes it easier to get where you want to be, even if what you've done has sucked grapes.

...funny. Writing music works the same way, too... and so does writing code.

The native iPhone hack I put together for the C4[1] conference is in the process of a "wow, I hope somebody can read this code someday" cleanup. I will release the source in the coming days. Stay tuned for a download link.

In the meantime, here are a couple of teasers.

Screenshots:

And here is some code for playing a sound file from your native iPhone Application's bundle (with the class-dump'd headers you'll need, too). The iPhone, as was mentioned by everyone with a native hack at C4, has some really intelligent API. Hats off, ladies and gentlemen, to the iPhone team. They must be having a grand ol' time internally playing with this thing.
