I am looking to pick up the HTC Thunderbolt whenever it gets released (crossing fingers for this month). I am under a family plan with the rest of my family, and am not the primary account holder on AT&T. We are switching to Verizon in anticipation of the iPhone 4's release. Everyone else in the family is looking to get the iPhone, while I want to wait for the HTC Thunderbolt. If my family switches over on the 10th (or whenever they receive their iPhone's), can I simply get a contract free verizon phone on eBay and use that (and port my number over and become part of the family plan), so that when the Thunderbolt comes out I can then switch over to a contract plan (and still get the subsidized price)? Any help would be appreciated.
