Switching back and forth between 2g and 3g?
I just bought a really clean 2g at a couldn't pass up price, I figured, worst case, it would be a good, cheap spare should my 3g be lost or damaged. Anyway, I thought I could just pop my sim card in and use the 2g without anything else being done. After installing the card it wanted to be connected to itunes which then wanted to activate it like a new phone, prompting menus that called for picking rates, plans, etc. I canceled out, put the sim back in my 3g and decided to seek some help.
