T-mobile Prepaid Data still available?

[hanguolaohu]

I'm using a Pwnage v3.1.2 unlocked iPhone 2G on T-mobile's prepaid plan. I'm dying for data but am not sure whether the T-zones hack still works, and I didn't want to try it as my current plan is I pay 10 cents/minute whenever I use the phone, which is a much better deal than the Sidekick's $1/day & 15 cents/min. plan. My question is:

How do I get data on my T-mobile prepaid plan?

I've researched this question on the forums already, but it seems that the situation keeps changing as T-mobile blocked iPhone users on T-zones in August.

Thanks.
