[kksugai]

OK, so here is my problem. This problem started today. It was working perfectly normal until a few hours ago. It first I get calls, but the mic doesn't pick up my voice so the person on the other line can't here me. Then after a few hours, it just starts dropping the calls without ringing and a pop-up comes up saying "This accessory is not made for this device" I try connecting to the wall, doesn't charge and the same message comes up. Computer...same thing. I tried to turn it off, but just does that circular thing and turns back on. It also began heating up ALOT. I'm running out of batteries soon so could someone please help me?? I do have it hacked, running 1.1.2 with installer.app. Any help would be much appreciated.
