verizon smart phone that will work international

[herm0016]

i live in colorado and work in Austraila. Right now i have a htc incredible 4g for the states and a cheap lg prepay smart phone for austraila. the only network i get where i work is telstra.

i guess the 2 countries use different frequencies for their 4g service. is there a phone that can i could use both places with just a switch of the simcard?

This would simplify my life somewhat, and simplicity is not lost on a guy who commutes 12,000 miles to work.
