[quote name='RiCeBo1']Yes I already have a contract, started last November
Don't plan on staying with T-Mobile after my contract ends, I can't get no reception at my area[/QUOTE]
Then I wouldnt waste money on the sidekick as you can only use it on Tmo. YOu may be able to unlock it and use the phone on another carrier, but to connect to the danger servers for internet, you have to use tmo.
Tmo does sell them for prepaid, dont know how much they are, though.
edit-looks like its $279 after rebate for the prepaid sidekick package, so ebay may be your best bet.
