I am not sure what you are doing here but unless I am misunderstanding your quoted prices, it is a minimum of $54.98 a month, for a total of $1319.52(and this is being kind, not including tax or other misc fees), meaning you are paying $934.52 over the plan, plus the cost of N900 if you are switching it to that. Even if you work out a text instead of data plan that is still much higher than your quoted $330 for 2 years once you include the cost of an N900. Sounds like a lot worse to me than just going to T-mobile when it comes out and getting a contract free 3G plan.
