so what do i do if i want to keep my messages and address book? Can I reformat without my SIM in the phone so I can keep my contacts? If not, after I reformat, can I load my restore data that I already have created? If I can't keep my contacts, it's not a big deal because I have it copied on my old phone, but it would be much more conveneient this way. And I don't have a data plan. That's not gonna be a problem for any of this, right? Thanks a lot JC.
