Hi, I have OOB 1.1.2 and was able to downgrade and jailbreak in 1.1.1. One problem that I have is my the iPhone will not sync with iTunes 7.5 on my iMac. It is recognized by iTunes but after making selection for playlist to synch, and pressing apply, the phone goes into sync mode but iTune synch just stop and iphone is unmounted.
if I use iTunes 7.4.2 on my macbook, sync works flawlessly.
Any help would be greatly appreciated.
