I just spoke with Verizon on the phone, & here's what they said: Global roaming won't be enabled initially, but they're hoping to have it active by mid-July ("prior to the London Olympics"). Said it will be a "true global phone", and will work in countries using both 850/1900 and 900/1800 frequencies. I asked specifically about a couple of 850/1900 countries to be sure (Honduras, Colombia), and she claimed it will work there & "all over Europe".
