Open source iPhone apps? Is this even possible? Apparently yes. Mobile Colloquy http://colloquy.info/mobile/ is available through iTunes App Store but its source code is also available in Colloquy svn repository. Anyone can check it out from the repository but not everyone can transfer it to an iPhone.

OK so what do you need to compile and use this app on iPhone:

• iPhone or iPod touch obviously, I only tried on iPhone
• XCode with SDK for iPhone I use SDK version for iPhone OS 2.2 and it works fine
