Urgh. I should have waited.
On September 9th after the "It's Only Rock And Roll" Apple Media Event, I updated my MBP to iTunes 9 and shortly thereafter updated my iPhone 3G to the 3.1 OS. I've had this iPhone 3G since Launch Day back in July 2008, and have luckily had great experiences in the past with my firmware updates from 2.0 onward. Not this time. Daily I experience at least 2-3 "comas", with today's culmination of 5 and a weird glitch where the phone rebooted straight to the Camera app, and each the Home button and the Sleep button only acted, when pressed, to take a screenshot of the display! Needless to say, another hard-reboot.
I've been following this thread for a while now, and I've tried the Apple Genius Bar. The Genius who helped me had heard of the issue, but said all he could offer me was a firmware restore, and even then he couldn't get my iPhone to accept anything BELOW 3.1. I walked out with 3.1 hopeful that it would work this time, but before I had even parked the car in my parking garage upon returning home I'd already coma'd out. I've tried restoring on my own, with and without backups. Deleted network settings, tried turning Safari-Anti-Fraud on and off, turning Notifications on and off, turning WiFi on and off - hell, I even tried the bogus method of leaving the phone charging with wifi on and Safari open to properly download the anti-fraud information - all to no avail. This 'update' has made this device near worthless.
By no means will I write off Apple products here, but c'mon Apple. QA: Quality Assurance. It's coding for 3 different hardware configurations - not 10, not 100, not 1000 - just THREE.
I'm left deciding whether or not I want to go argue with the Genius Bar again tomorrow, demanding some kind of replacement. My 1-year warranty is obviously out of effect here, but if anyone dare suggest I should have bought AppleCare for this device, I want to ask you one thing: Why should I have to purchase AppleCare to protect myself from APPLE THEMSELVES? My iPhone has no physical deformities, and I take pristine care of the device. All I've done to this device is upgrade it at Apple's OWN recommendation. If that doesn't warrant a fix of some kind from Apple, I don't know what does.
