Sometimes when i do not at all touch my Sony Ericsson Xperia X10. i keep on getting a text from rogers something like "You have attempted to use a data application without a data plan. For options, click here http://rogers.com/m/smartphonedp/0/i" and it really bugs me, since when i use internet i only use wifi from my router and when its not connected to a wifi router i get that text. how do i stop it?
