Bodyguardz is awesome, a little tricky to apply, but if you're careful enough you can get a perfect fit.

Not too expensive too, if you know where to get it.

Had been keeping my iPod Touch in my pocket together with my keys, cellphones, etc, without any problems at all. Improves grip as well.
For beginners I highly suggest getting the normal version, don't get the dry apply as the dry apply requires extreme attention, and it's very, very difficult to apply. You may need to wear surgical gloves to avoid getting fingerprints on the dry apply sticky side.

They come in two sets (2 screen protectors, or 2 screen protectors and 2 body protectors for the full coverage version), so you can replace the protectors if you screw up the first, or after your protectors degrade over some time.
