USBFever has released three different lenses that are mounted magnetically on the iPhone.
Wide Angle Lens for iPhone - Magnification: Wdie 0.67X + Super Marco - Lens Construction: 2 elements in 2 groups - Dimensions: 20mm (diameter) x 11.2mm (length) - Weight: 4.2g - US$16.99
I could care less about how it looks - functionality over looks.
.67x & .28x are good measurements...I just hope the lenses are okay...no blurring on the edges of the lens/picture.
