Missoula isn't on the list for 4G enabled cities yet (in fact nowhere in MT or WY is). Did she actually get 4G or was it linking up on the 3G network? I am over here in Butte and their 3G is slowish (although within expectations for 3G) but dependable when I need it. If she was actually on 4G I might actually take the plunge and upgrade my phone...
