I have loved my iPhone. Now it's more of a hate. Ever since I upgraded to 32 gig GS, it has been acting up. Nothing I can replicate at ATT store, because it happens randomly. People say they call me, it rings once and then there is silence. I drop a call, try to call back and get fast busy. I reboot the phone and then it works for 4-5 hours. Lately I have missed very important calls. The phone was not dropped or anything. I didn't jailbreak it. It just started acting up 2 weeks ago. ATT blames Apple, and Apple blames ATT. Since I can't replicate the issues at the store, I can't get it exchanged. Anyone else have anything similar happen?
