as for "cells" we call em mobiles in AUS

Sony Ericsson or Nokia are the way to go. easiest to use, best featured, good looking, as for most other brands, LG are quickly becoming cheap brand that aren't really trusted, Motorola are hopeless, m8 of mine had V3x... broke within a month took it back and got it replaced same sort of thing happened, had to live with it before i convinced him to go Sony

same thing with another mate of mine who had the same phone, motherboard literally blew, got incredibly hot and died, ive had at least 5 of each nokia and sony and not a single problem, except one sony where the charger got stuck... as for service providers... i dont live in America so i would have no idea which is best
