Harvesting an iphone

I was wondering if it would be a good idea to try to use an old iphone for its accelerometer or something else fun to play with or if the parts are too tiny and specialized to bother. Ive got an old iphone 3g with a dead battery and smashed screen. I know its still worth a few bucks in that state but not really worth the trouble of selling anymore. Has this been done? I couldnt find any info on removing and using an iphones accelerometer.

thanks

I figured that would be the case. thanks

I tried harvesting an old ipod touch (broken).
The components are too small.
You can get away with a nice lipo battery.

Well if it still works you might write an app to get the sensor values and just send them via bluetooth (or like it's possible on Android maybe even audio port or USB).
