    I'm all converted over to my iPhone 4. I plan on keeping my 3GS as insurance in case I damage my 4. How can I do a reset to factory wipe of my old 3GS without activating it now that my new phone is active for my phone number?

    Click restore, when it's finished and asks you how you would like to set the phone up, unplug the sync cord.
