TP2 & T-MO Prepaid - Internet options?

[quid246]

So here I am going to the US and thus "repatriating" my SIM and security unlocked VZW TP2 to it's native land.

Going to be in the US for about 2 weeks, so I am wondering what options exist are in terms of getting data on a T-Mobile prepaid SIM. I've read some people used to be able to use non-Sidekick phones on the Sidekick plan, but don't know if how true this or is even still possible.

Just need data for light browsing and e-mail... and don't really want one of these 1 cent per KB deals, talk about a rip-off!

EDIT: I know it would only get EDGE, which is not a problem.
