I was actually pretty surprised I didn't at least get the T-Mobile banner up top, said no service no matter which APN I used.
I tried more just out of curiosity, however sure would have been nice to have worked. A Free 200mb a month (and pay a bit more on the months you need it) portable device would have been a game changer - especially for those who who don't need voice or only use it enough that a VoIP service is sufficient.
