Hey guys!
I've got a bit of a problem here and i can't figure it out myself

At home i've got an imac which has my iphone synced to it. I'm staying at a different location and i won't have i imac at hand for a while. Instead i'm using my macbook now.

So, my problem is that i want to sync my iphone to my macbook but i'm afraid that i'll lose all my data (phone numbers, sms, etc) if i do that. Losing music is not a problem becaus my macbook contains the same music basicly but i don't want to use my phone numbers and sms and stuff..

Can anyone tell me how to do this? Because i've been listeing to the same music for almost 3 weeks and its starting to anoy me!

Btw, my iphone has a jailbreak and is currently on firmware 3.1.2.
I don't need a unlock to use my iphone so i can activate normally.

Greets to u all, rutger from the netherlands
