I have a question upgrading that's a little complicated. My mom ordered two vortexes BOGO over the phone with verizon. I read a few reviews and realized the vortex is not going to be very good for me. Online it still shows both lines as eligible for upgrades. Can I go buy an Incredible instore using my upgrade before the vortex arrives and have my mom return my vortex without opening it when it arrives some time this week?
