If I go to T-Mobile right now and buy the Sidekick LX for $299.99 with the $39.99 dollar plan and unlimited text messaging with no other featues and things that would cost more, how much money do you think I would be paying once I walk out?

well when i bought my sidekick3, all i paid for upfront was the phone. So I'm pretty sure thats all you will have to pay for there at the moment. Then they tell you when you should be expecting your first bill and whats gonna be on it.
