Earlier this year I gave my original iphone to my son. He stuck his sim in it and I called ATT to get a data plan for him. They put him on the only data plan that exists for the 2G iphone. $20 per month unlimited. (can't pump that much data over Edge I guess) Less than a month later I bought a 3GS on eBay for him so I wouldn't have to listen to him complain about the 2G anymore. He stuck the sim in the 3GS and I never bother to call ATT but the next month they charged me $30 per month for unlimited data. He's had unlimited data for a number of month's now. (sad thing is he doesn't really need it but the minute I cancel he'll start cranking thru data like his sister that keeps going over each month) Obviously this "technique" isn't practical for everyone and might be a loophole that ATT has since closed but figured I'd share. ps..bought the 4S this morning at 7:00CST from apple.com...took less than 3 minutes.
