I've had my 8130 for over a year now and it's worked fine. Recently it's been resetting (as if I pulled the battery) about 2-3 times a day. I have Jivetalk, myspace app, and the amazon app installed. Also, it's not letting me delete multiple contacts that it's created when I sync it with pocketmac. I uploaded 4.5 on it months ago and didn't have any problems until recently. Any ideas? It's starting to get really annoying...
