I know everyone likes the N series from Nokia, but does anyone use other phones? I'm still debating what to get I like the N82. How does it compare to the N95 everyone loves? Anyone know anything about the Samsung i7110 yet? How about the Sony Ericsson C905? Also, in looking around I don't even know what is for what network. For the US networks (specifically AT&T) what am I looking for? Will the above phones even work?
