Olloclip all the way,
This review is from: Olloclip 3-In-1 Fisheye, Wide-Angle and Macro Clip-On Lens System for iPhone 4 and 4S - Red (Wireless Phone Accessory)
This has to be the best add on accessory for an iPhone 4 or 4s. I've had one since summer '11 and I'm always using it.
It's easy to use, you have the choice of three add-on lens' to compliment the awesome iPhone camera. You get wide-angle, fish-eye and marco all in a nice and simple design.
If you purchase this and camera+ from the app store, you'll have the two best add-ons for an iPhone.
