> So as a phone it works great?
So far for me it has yeah. I really don't know enough about how well it works outside of the US (but many of the devs seem to be in Europe, so I imagine it works well there?) For me the biggest thing that hurts is battery life, but normally I am in areas where I can just plug it in, so it isn't a big issue. If I am out and about for a day, I just carry around a battery pack (or a spare battery).

You could probably get an EG-25 USB modem and play around with it, but AFAIK no one is doing that, so you'd be largely on your own.
