Hi. I currently have a Motorola Droid 1. My two year contract with Verizon has long expired and I'm going month-to-month now. If I go and buy a Droid 4 outright (that is, pay the full price of the phone without going through Verizon's upgrade+contract extension thing, either from a Verizon store or from another merchant) what is my experience going to be like when I try to activate my new phone with my Verizon number? Can I do this without any changes to my account? Am I going to encounter difficulties given that my phone is 3G and the new phone will be 4G? If it's a problem, can I proceed anyway using the Droid 4 as a 3G phone if I were willing to do that? Thanks.
