Hi guys, This is my first post and I must say I'm a newbie when it comes to computer and stuff like this. I currently have an Iphone 3gs with the firmware 3.1.3 (the one before 4.0) and its jailbroken. I have a few questions: 1 - Is there a new version of jailbreak for the firmware 4.0? 2 - How can I upgrage to the firmware 4.0 if my Iphone is jailbroken? 3 - Will I lose anything like my contacts and txt msgs if I upgrade? 4 - what is the latest firmware for my iphone? I think you know where I'm going with this. I'd really appreciate some help of possible.
