So my ATT&T bill came in the mail today, so I open it up and see a bill of 377 dollars! WTF? I knew I upgraded to 3GS on the 19th one day before the next billing cycle so they can charge me the extra 10 for the 3G data plan. When I got my 3GS it said I had no data plan and canceled my 2G iphone data plan. I had to call ATT for them to add it and change my IMEI number. Which means I was charged for all that data. Now I have to call ATT and hope they refund my money because it clearly states I have an iPhone data plan on the bill. Anybody else got this problem?
