My problem is that (according to ATT's data usage chart) we get 'random' large data hits being sent from her phone while at home on our wireless network. The latest culprit was a 154MB 'file' sent from her phone by Internet/MEdia Net. Is there a better way to see who/what is causing this than using ATT's site? Why does it use ATT data if it's on our wireless network? Of course ATT and Apple haven't been much help. At least MR folks know what they are talking about... Thanks in advance.
