Hi guys, i have a emergent problem for my iphone 4.
My old computer crashed. I now need to sync my iphone to a new computer. How can I do this when the iphone is only made to sync to one computer? help please!

How do i copy all my music from my old itouch to the computer/itunes,so i can put it on my new itouch.
PS: My OS is Windows 7.

Hi. My Mac's hard drive recently crashed and everything is wiped out. I have a new hard disk now.
My question is: How do I transfer data from my iPhone... back to my Mac? I would like to transfer data from my iCal, iTunes, iPhotos, SMS and contacts.
Would appreciate some advice. It's been a very frustrating experience. I don't want to screw up and end up deleting all my data from my iPhone instead.
