Part 1:
what are the major differences between 8320 and 8330
i know they have different cariers, i know they run different systems... what about hardware though?
like camera
speed
etc.
Part 2:
i just got the verizon curve, and i cant be without it... im going out of the country for 2 months maybe more...
i just learned that if i had wifi on my curve that i would be able to make free calls as long as i was connected to a network... so lets say i got my hands on an unlocked 8320 and brought it with me, would it work there

now to me it seems obvious that the 8320 is a million times better than the 8330 because of this capability, so am i wrong/ are there things that the 8330 has that the 8320 doesnt have?

and finally if yes, is it worth sending back my 8330 and canceling verizon and moving to tmobile for this phone?

thanks for your patience
