Its jailbroken 1st gen 2.2.1 I use Cydia. I don't understand why my phone keeps crashing! i'll be sending a text message and it'll restart. or i'll receive a text message and it'll restart. I open cydia and it restarts! it's really frustrating and I already restored it and re jailbroke it. it hasn't made it any better. so i'm asking what is it that i can do??
