Ok, so here is the deal. I want to buy a Blackberry 8520 for my t-mobile account. I am currently due for an upgrade. I already resigned my contract but did not get a new phone because I couldn't find one I liked, the one's I did like required a data plan. What I want to do is go over to the tmobile store, buy my blackberry, let them change my contract there, then later call back and tell them that I don't want a data plan. The reason I don't want a data plan is because it will raise my bill from 50 to 90. I am a poor college student, and I need to save where I can. If I do this, do you think that I it will work, or do you think they will end up charging me the full price of the phone in the end?
