Recently, I purchased a set of camera phone lenses from Photojojo that fit onto most phone cameras.  The set includes a Fisheye, Macro and Wide-angle lenses for $40.

Pros:

• Great photos from your phone
• These are small enough to fit in your pocket with your phone and come with covers for both sides of the lens.
• Quickly attach over your lens with the magnetic base on the lenses
• Magnetic lens covers with lanyard so you can safely keep these secure with your keys, bag or in your purse, etc..

Cons:

• Hard to hold since so small.
• If you arent using the included magnetic ring mounts on your camera, have to hold steady so the lenses dont fall off when you move the camera around quickly.
• Have to remove the lens each time from your camera when putting back in your pocket.
• Taking photos with your phone is not as inconspicuous with these attached.
• Fisheye lens has a bit of distortion at the edges with causes you to capture the inside of the lens

See for yourself below in a comparison of images with these lenses and the basic phone camera lens and look for more of these incorporated into Is This Houston?
