Want to update gs 3.1 jailbroken phone to 3.1.2 jailbroken phone
I have an iPhone 3gs 3.1 that was jail-broken with blackra1n.
I would like to update my firmware to 3.1.2 and keep jail-broken. I don't think its as simple as updating via iTunes then jail-breaking again... this is why I'm here. I obviously have a few questions and am looking for some direction in doing this. Can someone please suggest the steps that need to be taken to complete this task?
The computer I hook up to is running Windows Vista 64 and Linux (Ubuntu).
Is there a way to keep my contacts through this process? I already know how to pull my videos/photos from the phone. Are there any negative aspects to doing what I want to do?
