Hi I am new here. I was searching online on how to get the latest OS4 on a jailbroken iphone and found a TON of info. I want to be safe so hopefully you guys can help me out. Stats: Iphone 3Gs version 3.0.1 (7A400) Itune version 22.214.171.124 Jailbroken with redsn0w a long time ago. How do i go about updating to OS4? and jailbreak it? will i lose my contacts/apps/photos if i update? can someone guide me step by step? or at least point me to the right direction? Thanks in advance!
