Ok heres the deal. I currently have a family plan with 4 lines. last week i started a new job had to use an early upgrade to but a smartphone. I got the DINC 2 which I am loving but stupidly paid way too much from an authorized verizon dealer who waived the early upgrade fee. But i still paid $199 and later found out Costco has the for $79 with accessories and 90 day return. So now I have 4 days to return BUT I feel dumb getting a 3G phone knowing I am missing out on locking in a 4G plan before the tiers go into effect. But i reall dont want to be married to any of the 4G phones out now and I only can do one exchange. Ultimate goal is to get the Sammy GS2. So heres the plan please tell me why it wont work. I return the DINC2 and rollback upgrade. Cost $35 I add a line to family plan at Costco and get a TBOLT to hold me over. Transfer old # to new line. Exchange TBOLT when sammy is released. Cancel old line. Sounds like a plan?
