right now im on a rogers 3 year contract and i have an lg xenon. i've only had it for one year but i want to upgrade to the torch for christmas. if i were to upgrade and get a data plan, would that be added to what i already pay for my phone now? or can they just switch it? also will i have to pay the full price for the blackberry torch? my current phone does not work if that makes a difference. thank you!!
