Alright, who's using video game ringtones for your cell and which ones are you using?
I've found 8-bit video game midi files translate well to phone, and use the Lost Woods theme from Ocarina of Time for incoming calls from my wife, but I've also used themes from other areas of Ocarina and Dragon Warrior from the NES.
A colleague a couple cubes over uses the 1UP sound from Super Mario Brothers for incoming texts.
