One of the most visually pleasing iPhone applications is 9-Toolbox. Better yet the visuals are matched by functionality. It’s like 9 apps in 1. Some are more useful than others, but overall it’s a great application.
Until the end of April, they’re offering it for free.. so get in quick, there’s only 2 days left (3 if they’re working on US time).
The heads up on this one come from winandmac.com, a great site, if you haven’t checked it out, i recommend you do.
