Open Source iPhone Applications


Below you’ll find some of the more prominent open source iPhone applications available for free download on the Web. The iPhone is brimming with paid apps, but with the advent of the Google Android platform and the surge of free and open source apps that it promises, we’re now starting to see a much welcome growth in iPhone open source projects. I’ll keep this listed updated as and when I find new software. If you have a suggestion to add to the list, please leave a comment and I’ll include asap. Enjoy!

Good read. What I don't understand is some of these Apps, although free, don't have any form of advertising within the App. It makes a change to get a free App and not be bombarded with adverts. Have to say I use the hp calculator a lot.
