Quickoffice emulates what we think of as an office suite on a desktop. While you probably won’t wish to constantly edit documents on the go, it is definitely an office suite that is robust enough to meet most users’ mobile needs.

The Tiffen Company has brought their digital photography filters to the iPhone as Photo FX. Even if you use Photoshop to edit pictures on your computer, Photo FX might be just the thing for a quick tweak on-the-go.

This neat photo editing application lets you selectively highlight areas of your photos with color. It produces such nice results with so little effort that you may actually find yourself putting photos onto your iPhone just to use it!
