I have 3 lines on AT&T right now (mine is the primary). I recently bought a Droid X on Verizon to try it out during the 30-day trial. I want to switch my wife and mother over to Verizon as well, but they have about 7 months left of their contracts. I thought I read somewhere that Verizon periodically does credits for adding additional lines when porting from another carrier or something to that effect? The Verizon CSR said they have done it twice this year, but didn't know when they would do it again. Not sure exactly how it works or if I should wait to port them over until this credit happens again?
