Hi people, I am from Singapore. Lately I have been experiencing alot of problems after jailbreaking. Now I do not know if it's the carrier's fault or the phone's fault, OR the jailbreaking fault.
I have restored my iPhone4 from a jailbroken 4.1 to an unjailbroken 4.2.
The problem is that it always shows me No Service, after many reboots. I have resetted network settings, resetted ALL settings, the airplane mode method, and the ultrasn0w method.
I am desperately in need of help.
I do not know wether this fits into this forum topic, but if it is not, Moderators, please help me move it to a suitable place
If you now at 4.2.1 and your iphone is with official carrier or you have a factory unlock & you are getting no service, i suggest you take it to apple store in SG to get a replacement.
Unless your iphone uses software unlock, upgrading to 4.2.1 will also update your baseband and there is no unlock tool to unlock this current baseband.
