Jailbroken iPhone OS 4.1 wont sync apps/music

[AdmiralAdama]

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, however, copy music i've downloaded directly from itunes store onto my iphone back into my itunes. It will sync contacts.

I'm using itunes 10.1

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? How to figure it out?

Restore to 4.1 and jailbreak with limerain again.
