I was wondering if there is an app that would allow for the iphone to vibrate randomly throughout the day? I would love it to do that in my pants. it would be like an unexpected "pick me up" to help me get through the day and the best part of it is that it would be caffeine free so watch out coffee!!! You've been replaced by the iphone. Hmmm... Maybe the commercials are right and there truly is an app for everything.
