All you have to do is to ADD another line to your phone, so for everyone just add a new phone number ie, the fair and flex plan for families with 2 phone numbers and you can get the 150 INSTANT rebate on this phone I will order my 650 in a couple weeks hoping all the problems will be resolved with memory. I hope that i dont have as much troubel with the 650 as i did with the 600, that thing was trouble from day one!!!
