My friend and I made a weapon timer app for Android. It works in MLG custom settings and Slayer/TeamSlayer playlists. You just tap the weapon when you or someone else picks it up, then it will notify you with a sound 20 seconds before it spawns and when it actually does spawn. It can be found on your phone by searching "Halo Reach MLG Timer" or "Tom and Frank" in the Android market.

Damn. Can't find it in my 1.6 android market. Guess you have to have 2.0 and up
