I called Sprint a few days ago and said that I dont like the phone I currently have and am interested in getting the BB Curve 8330 but since I am not eligible for an upgrade it is about $550 to buy from them. I mentioned that other carriers were offering very good deals on them i.e. Verizon is offering for $99.
After a few minutes on hold they changed my account so that I am eligble for the upgrade at a cost of $99!
