My MBP is coming in a week and I'm not sure how I'll do this with my jailbroken 3GS. Is it okay if I back up a jailbroken phone? I haven't backed my phone up since I jailbroke it (about 2 weeks ago). Is there a Windows folder for which I can find my backup and transfer it to my MBP ( I have an external HD). Then I put all my songs and apps on my external HD and transfer it to the library, will it let me do that? Or do I just tell the MBP to transfer purchases after I authorize it to use my account? Or should I restore my phone before I use it with a MBP? I want to keep the jailbreaking, so do I have to do a purplera1n jailbreak with Mac again, or keep my current jailbreak without restoring?
