My story - 1. I got an iPhone 3gs with cydia installed on it (iOS 4.1.3). I didn't knew if it was unlocked or what since this is first time I am using iPhone. 2. I upgraded it to iOS 6.0.1 using itunes then I was stuck at the activation screen. 3. Someone suggested to jailbreak it so I did following a video from youtube. Everything went well and i manage to jail break it. 4. Now the iPhone just keeps 'searching' a sim when the sim is inserted and it shows 'no service' when the sim is not inserted. So guys need help solving this problem. As far as I have read.. I think I can do two things here - 1. install ipad baseband using redsnow.. OR 2. install ultrasnow from cydia and the fix.. The problem with first is that when I connect my iPhone to redsnow and go for iPad baseband there is a big notification that pops up saying that I might brick my radio signals for ever if I go ahead. So I am not sure to go ahead or not. For second option, I really dont know if I do it since I have seen people doing it only after installing ipad baseband. That's it.. guys help me solve this network problem please. Model No. MC131X Serial No. 829510..... I think I have the new bootrom.
