Thats an easy one mate!
Just restore it... Then when it asks just label it as new instead of restoring from backup...
Now if your referring to the at&t part i'm not 100% sure about that part of the switch I'm an ebay fan...
anything else I can help u with mate?

Thanks,
Do I take out the sim from the 2g before I sell it off?
My 3g came with a new sim from AT&T
