Verizon Galaxy Nexus roaming and unlocked question(s)

[SterlingSpring]

I can see the Verizon Galaxy Nexus (or CDMA) version has Verizon's 3G Ev-Do frequencies built in along with LTE band 13...(or the 700mhz LTE spectrum as they call it...) does it have any other frequencies built in? An Unlocked Galaxy Nexus I mean..would it work with HSPA+ (the international ones) or EDGE overseas? Any other LTE bands?

Curious to see if this phone would work as a roaming phone on something over than Wi-Fi...
