Stands for Ghetto phone. The available "free" phone that you get when signing up for cellular service-cause you can't afford the cool full featured model (or you lost it and can't pay full price for a new one). The G-phone model usually lacks style, functionality, and reception--is thick, has an antenna and an old school earpiece.
"Man, I lost my blackberry, so now I gotta use this G phone until I can get an upgrade."
"Can you hear me now?"
