A friend of mine bought one of these because he thought it would be cool. And it was pretty cool, though keep in mind, it's just a phone. so my friend ended up getting an iphone (well, a friend of his broke her iphone, so he got a free broken iphone, and being that sort of person, he successfully repaired it.)
Anyhow, once I visited the guy and I left my phone charger at home, so after my nokia e90 died, I borrowed his third world phone. My t mobile sim 'just worked' and it seemed like a fairly competent phone overall... but really, voice communication is only about 10% of what I use a phone for, and that's all this thing can do, so for me, it's of limited utility.
