Just wondering if anyone else has encountered this. When my battery is empty so I can't turn the phone on, I put it on charge and once it turns on it has reset the system time and date to 01/01/70 01:00am. Not only that I can't open any 3rd party apps. They are technically opened and appear in the multitasking tray but they close/hide immediately after they are tapped. No problems with the pre-installed Apple apps, but anything out of the appstore is problematic. I have to sync it to get back functionality, and have to set the date and time manually (and click through several hundred alarms from the calendar app)! Applecare are sending me a box to return it. Anyone had these problems? The service rep said she hadn't encountered it before.
