Ibrate is a app that turns your phone into a vibrator. saw it on leno last night. I guess it would be better than a vacuum...
X10 on the otter box my I phone is a year and a half old and still looks brand new inside the second otter box.
another app that i like is dragon you just talk into the phone and it spells it out as you talk then you can text or email what you said... if you talk like i do "redneck" dragon has some trouble writting some werds.
