Hey do you guys know if their is a way to sign for a 2yr contract on t-mobile and get like a $200 rebate except without having to purchase one of their phones.

Im thinking of ways to subsided the N900. I heard of an example where someone bought a really crappy phone on t-mobile with a 2yr contract on amazon for like -$150 and then just buy an N900 from amazon unlocked. Is there a way to do this but without even buying the crappy phone and just getting a contract? I saw on ebay a company selling Xperia X1s with 2yr contract with t-mobile for a discounted price too.
