Just got my AT&T bill for $177 which seems excessive. Apparently they're charging me an extra $95 this month in "Mobile to Web" usage fees. The Msg/Min/KB used field says "4901". I'm going to call them up of course, but figured I'd ask here first since surely someone else knows what this means? I thought the iPhone plan had unlimited data usage? I rarely even use my phone, this past billing period I used a grand total of 85 minutes of talk time and sent 54 text messages.
