Here is a simple solution to a minor problem. On the iPhone 3G, we’re always covering up that single tiny speaker with our huge hands. That’s where SoundClip comes in, a $7.95 attachment that will give you a slight sound boost.

It’s not exactly an amplifier, but TenOneDesign says that it passively enhances the sound by a noticeable 10 decibels. It attaches to the iPhone’s dock connector and should serve as a good reminder to keep your meaty fingers away from it. It clips onto the USB cable you use to charge your device, so it won’t get lost.
