Since the sidekick lx is 199.99 with a new contract how much is it if put on an existing plan?

$ 300 But If You Already Have T-mobile It May Cost $ 200 Or $2.25 Or If Yhu Already Have A Sidekick And You Want To Trade For Another Sidekick In Some Stores It May Cost $50-$100 To Trade

right now it cost $130

i do not know

Now, the phone cost $225 from tmobile.com.....its quite cheap from there...!<< yeah and the sidekick 09 cost $250 NOT cheap!

i think it cost 330 omg cacacaca<< that's a dumb answer no offense though it depends which hiptop(sidekick) your talking bout just a sidekick Lx or an sidekick lx 09. Sidekick lx 09 cost 250...
