I need to know how to buy the phone and how much it will cost.How do i get the best deal on this t-mobile phone?Depends on where your contract is. If this a new line or if you've had your current phone long enough then the KRZR will be $200 with $50 MIR. If you haven't had your current phone long enough you may qualify for a partial discount which would be $200 no rebate.
