Hello, I recently jailbroke my Iphone 2g 8GB. using Quickpwn 2.2-1. My iPhone was working already 2 weeks. No problem at all. Now suddenly I tried to make a call and i saw 'No service' So I thoguht huh!? I rebooted my iPhone and still no signal. Tried taking my Sim out and put in again. Still nothing. I tried using the simcards from my parents. No luck either. It just says No service or searching.... forever. How do I solve it? Thanks.
