iPhone 4 total malfunction after iOS 5.1.1 update
I updated my iPhone 4 to iOS 5.1.1 on Friday, it worked normally for about 24 hours, and now all of a sudden it is completely unusable. If I press the home button absolutely nothing happens. But if I plug it into the charger and then press the home button, the white apple appears, and it boots to the grey screen that you get with a brand new phone. When I then swipe the slider I am asked for a passcode, so I enter the one I used when the phone was working normally. I then get the screen that says to connect to iTunes. Problem is that I'm traveling and so for the moment cannot connect to my iMac at home. (I have a PowerPC G4 laptop with me that can't go beyond OS 10.4 and iTunes 9.1.1.) Can anyone shed any light on this? Is there anything I can do now or do I have to wait until I return home? Or is the phone totally toast or what? I've read some stuff about SIM cards being corrupted with this update. Would a new one restore the whole phone?
