Hello, my mother and I share a phone plan and both are interested in the Droids. I currently have an EnV3, and really would like to upgrade. I was wondering if the Verizon BOGO works under a certain circumstance. We both have a 2yr contract currently. Hers ends in April. Mine in August. Could she buy a Droid, then get one free, so we could both upgrade? Or would I need to start a whole new line for BOGO to work? Thanks.
