Called Phlash, it's really the world's first external flash adaptor for all cellphones and so it's a great addon if your phone doesn't have a flash feature or is night blind :). Measuring just over 1 inches wide, it's kinda cute looking and can be either stuck or hung from the phone. To use just squeeze (err.. press) the Phlash button, when you click the capture on your phone.

 

We like it, and Phlash claims to be 12 times brighter than regular LED's, which is good for taking night shots. Currently Phlash is available for $19.99.
