How Do I Transfer My 3Gs To IP4 On A Different Mac?

[Flyin Ryan]

I've always synced my iPhone 3GS on my macbook pro which is running Tiger. But iPhone 4 requires atleast 10.5.8. So how would I restore from my backup on a different machine? (I'm using my Powerbook G4 12" running Leopard). I really don't wanna type in all these contacts again.

Thanks!

Authorize the new Mac, hook up the phone to iTunes, backup and sync. Hook up iPhone 4 and restore from backup or setup as new and sync.
