I recently hooked my V3 razr up to my laptop with the motorola mobile phone tools cd. once i had hooked it up i went from little to no reception to near perfect. the laptop is on wireless internet so i figured it is either somehow using the internet to make calls or it is using the wireless router as a repeater. but in either case would AT&T be charging me data charges? i know its kind of confusing but i just want to make sure i dont get a huge bill at the end of the month.
