OK, i have just bought a jailbroken iphone 4G running iOS 4.1 and with firmware 02.10.04 However, when i connect it to itunes, it will not sync up any music or apps. it will sync contacts. I'm using itunes 10.1 -- should i try to sync up with 9.2? it says it's syncing, but will not transfer any music or apps, and quickly skips from step 1 of the sync to step 4. Any thoughts on why this is happening and what can i do about it?
