I have used it quite a bit here in the U.S., even before it was officially released. Works like a charm.
I have NOT verified, tho, that billing overseas works as stated. I'll try it in Costa Rica in a couple weeks.

I find the interest in this T-Mobile WiFi phone to be curious at best. You are using someone else's free bandwidth and getting charged "air time" by T-Mobile. For T-Mobile it seems to be the best of both worlds. I suppose the best thing is that it works but I think I'd want to find a system that allowed me to use something like VoiceStick when I'm on a WiFi hotspot and GSM when I'm not.
