iPhone Hackers: Red-Rome Developer Challenge
As I mentioned in an earlier post on the iPhone activation hack, the community of users determined to hack the iPhone is really gaining momentum. The goal is to deliver not only a working unlocked phone, but also to pave the way for 3rd party application development as well. While there have been some minor setbacks this week, I noticed over on the iPhoneWebDev Google Groups page that a contest has been sponsored to stimulate some activity and maybe bring in some new users to take a crack at iPhone. If you are knowledgeable with ASM, reverse engineering, or other programming disciplines you should check it out.
If you are just another Apple fanboy waiting on the unlock you may want to start at the iPhone Dev Wiki.

Latest I have heard is that the guys doing most of the heavy work on this have segmented into two groups and are withholding information from each other. There are now 2 SVNs as well…one is public (with little activity), and one is private (and very active).
good news!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
