Jail Breaking Iphone 3.1.2 ( IM new here )
Hello iphone users, recently i just bought a 16 gb black iphone 3GS from my friend. He didn't jail break it yet ( not sure if you can). I dont neeed it unlock, because its locked to my provider. I have a few questions as well..
1) What program do i use to jail break this iphone? Could anyone provide a link for turtorial as well?
2) I heard jail breaking 3.1.2 is unstable and really buggy?
3) i Still have warrenty, does it void my warrenty?
4) if i messed up, how do i reformat my phone back to orginial?
5) if i messed up, does it automatically update to 3.1.3, which i was told not to ever do
6)any tips/warnings i should be aware of when im jail breaking the iphone?
here is the details
Version : 3.1.2 ( 7D11)
Modem Firmware : 05.11.07
Thank you !
