I also have a box of IPhone 5 still sealed. I have to bring it to Apple and do a return and buy it back to full retail no contract. I pre-ordered it at apple.com but instead of letting me get a non contract phone at the time it processed a new contract phone line. So now I have to go to Apple Store tomorrow to get this straight. I want to open it badly.. But I don't wanna risk my UDP.
You can open it up activate on dumb line then go grab any 4G sim, cut it down throw it in your Iphone 5 (write down the sim number first) Call VZW and bam UDP on your i5
