I am happy to report, however, that Google has allowed the program to return for users outside of the States. Still (and this is the question everyone seems to be asking), is it Google's place to enforce T-Mobile's TOS here in the States? And more importantly, should we lay down and let a multinational corporation dominate and suppress community-driven technology?
Well, I don't think so. So here's a post with the app, which requires a root access. There's a link in there for another root-required app called aNetshare. PdaNet is a non-root solution.
I should say that I don't officially recommend modding your phone. You could end up with a pretty strange-looking paper-weight. Having said that, please resume learning, exploring, and creating the software that drives the industry. Have fun!
