The Voyager does not have wifi, and even though its an LG it does not have as nice a menu system as the AT&T LG phones.
Verizon makes them use their menu system and its relatively painful. The new LG Versa is supposed to break out of Verizons old UI. But it does not have wifi.
For wifi if you dont want a Blackberry I am afraid you will need an HTC. I believe its called the Touch Pro at Verizon and has a different name with other carriers. There is also the Samsung Omnia, which seems to break away from the clunky Verizon interface with its clunky Windows Mobile interface.
