Hey guys. I recently bought the new iPhone 3G, and just jailbroke it. But fore some reason, i can't get any service at all. Well, at least I only get 1 bar, not the NO SERVICE thing at the top. But it has been stuck there, even after reboot. I even took out the SIM card and put it back in, but it didn't work. If any of u guys know how to fix it, could u respond back? Thanks!
