I'm thinking about getting the Razr Max to replace my Droid X2 and give the X2 to my dad. I see that I can select "keep unlimited data plan", so that is good. However, has anyone who got the $20off talk and text + data promo able to keep the discount for sure? I'm almost thinking it's not worth even changing and paying the extra through Verizon. Also, the line due for an upgrade is not the one I want to use the phone on. I usually just order it and call up, manually "agree to the contract terms" and then swap the ESN to the line I want without activating on the one I don't want it on. I wonder if that will not go quite right as well. Has anyone with the promotion done this? Thanks.
