Jmills87,
I have three ATT IPhone 4's that I am trying to jailbreak (tethered or untethered)so that I can use with my T-mobile sim card:
1. IOS 5.0.1 bb 04.11.08
2. IOS 4.3.5
3. IOS 4.3.3
I tethered jailbroke the first two with my win xp pro laptop using redsn0w without any problem by following the instruction on this forum but when I tested it with my working t-mobile sim card, it won't take it. It says something like not valid. I tried two different working micro sim cards, it says the same thing. Am I missing something here? Please let me know what to do next.
On the third one (ios 4.3.3), I've been trying to untethered jailbreak for the last couple days by following the same steps with no success. Towards the end of the jailbreaking process when it rebooted right after all the unix codes loading on the iphone screen, it showed the white apple logo for two days. I repeated the same process several times and it stucked at the apple logo. Right now it is on the IPhone original state as if I just bought it from the store wanting me to use itunes to restore and update. ITunes says it is in recovery mode and wanting to restore and update. How do I restore it without updating the ios since I want to preserve the original ios 4.3.3? Thank you for your help.
