I imagine the Sprint and Verizon will launch this phone at almost the same time. We saw Sprint's verzion leaked first and now this verizon model looks identical.

EVDO in the US
GPRS anywhere there is a 900/1800mhz network.

One downside to the verizon version is that it will most likely be locked to vodaphone internationally. Verizons other world phones have had this restriction whereas Sprint's have been unlocked.
