When I purchased my 3G S on launch day, I was able to switch my original 3G to a second line with AT&T at $9.95 a month after activating the 3G S. It meant my 3G iPhone was a full featured phone, just no 3G service. The WiFi worked perfectly though so I felt fortunate that I got a pretty good deal. Fast forward to yesterday when I was charging my 3G S and was tooling around with the 3G spare when I noticed 3G in the upper left of the phone screen. Up to this point it only had AT&T there along with the bars. I opened up Safari to see what would happen and sure enough, full internet service via 3G! I bet you anything somehow AT&T upgraded this phone and now I'm paying for a full service iPhone- really something I don't need nor contracted for. Edited to add: Having the extra phone (without the data plan) is worth $9.95 a month even though it is used sparingly, but having to pay the addional fees will be a bummer. Is anyone else experiencing these issues? Is AT&T going through customers service records and upgrading service that was not requested?
