I have had my iphone since about April. I started off with AT&T and used T-mobile as my main phone. I found out how bad ATT was around this area and the coverage was terrible compared to Tmo. So I decided to jailbreak my iphone after OS3 was released, i unlocked it and slipped in my Tmo SIM and have been using the iphone with Tmo for about 4 months now. I canceled my ATT plan as well. But when I purchased my iphone I had purchased the Applecare for the phone.. now that I am not a legitimate ATT customer, does this AppleCare still stay intact? If anything happens to the phone/battery/defects If I unjailbreak and restore will I be able to get the phone fixed?
