So as I was texting my friend this morning, my phone suddenly turned off, this has happened to me before, but I've never had trouble with simply turning it back on. This time, I tried to turn it back on but after the phone loads for a while an error message shows on the screen "App Error 205" and then it gives me an option to restart the phone. But even if I restart it, the same erroe message pops up. I've tried taking the battery out, but no luck. Has anyone else encourtered this problem? Or have any ideas how to fix it?? Thanks.

It sounds crazy but if you have a memory card try taking that out then restarting. Also what new have you done with the phone like new applications, maybe that will help.

Could also be a bad SIM.

But my best guess is to reload the OS.
