I own an iPhone 3g. About 4 days ago, it crashed for no reason at all. A screen popped up that said I need to connect to itunes and restore. I did exactly as it asked. Every time I turn the phone off and power back on, I get the "connect to itunes" screen. I'll restore and my phone will work for a few minutes, then I'll lose reception. If I get reception back and try to open an app, the app will close as soon as it open. I have restored from back-up, and also restored from "set up as new phone". Still the same thing. So I went to the genius bar today. The guy checked for water damage. He found none. He ran a diagnostic test. He said the test showed no problems with the phone. He did what he called a deep restore since the restore screen was there when I gave it to him. He even added one of my apps to try to recreate the app crash problem. All seemed ok. I left the store but hung around the mall in case it happened again. Sure enough, within ten minutes the restore screen was back. I took it back to them. They were going to replace the unit but it was 30 days outside warranty and I had not purchased apple care. They told me they would sell me a refurb with a 90 day warranty for $199.00. I didn't bite because I can't trust a refurb if my brand new unit gave in after only 13 months. Went to AT&T and they suggest that I buy a GO phone and put my sim card in there till I decide what I want to do. What I'd like to know is, has anyone else experienced this type of problem with their phone. If so, what was your solution?
