Get an att Tilt, skip the iphone..its a gimmick phone... if you want the iphone wait for the next gen one to come out...
theres nuthin like having a keyboard to type on, the capability of adding your own programs on it, ability to use msoffice mobile, push email all on the same device plus be able to do the same stuff ass the iphone like movies, music, pictures and surf the web...
I have the tmo wing and just got a new job where i get a discount with att, so i might get the tilt myself, iphone is up there for a good price though but i also hear it has bad reception.
