Hey there. You seem to know a lot about all the software jailbreak/unlock scenario.

When I get my new phone, should I restore it from a back-up of my current v1 or start completely fresh? If I do it fresh, is all I have to do regarding apps and stuff just sign in to my iTunes store account?

And if I do it off the back-up, what would happen if I plug my v1 back in afterward?
