Topic pretty much says it all - I'm not exactly sure if it's possible, I don't think so but maybe someone knows a solution.

I'm often walking through Paris and use my iPod touch (2.2) meanwhile. Sadly some of the best Parisian radio stations aren't supported by any of the available BlackBerry apps while they have their own apps for the iPhone / iPod touch. :/

This question has been asked and answered multiple times. AFAIK the answer is still no.

Nope. No can do AFAIK.

Would have been cool if it could be done though

Look at the soon to be released Verizon MiFi 2200.

I thought it has been released, I remember reading about it on engadget, as well as I believe Sprint as one as well

That mifi is and the associated data plan is darn expensive as well. Typical of Verizon as well.
