I have an iPhone 3Gs for about 18 months. Lately; it's been getting sluggish. It's the 8 GB model. Suddenly, a message appeared about disc space very low then the screen turned-off and the Apple logo appeared. The logo wouldn't turn-off four hours until the battery ran-out. I brought to AT&T, the carrier and they said the unit was off-line. What's up? I am now stuck with a 2 year AT&T contract of $88/month no matter if the phone works. I even tried removing and re-inserting the SIMS card. Any advice? Thanks. I love this phone; she's like my family! I already did the Synch into my PC which took over 1 hour before the break-down. I understand, if repaired, all stored info and apps will be lost including photos. Could I re-synch all info back after repairs or is all lost?
