I’ve been searching the web to find out if any of the iPhone Applications in the App Store are open source. So far I haven’t found any. How about you?

Is the Apple $99 iPhone developer tax too steep of a barrier?

Will WordPress for iPhone be among the first? The most popular?

Tuesday Update: I somehow missed Matt’s article on this topic. It does seem that WordPress will be among the 1st.

Many of the commenters including Scott Wallick would like to see a WordPress app on their other brand of phone, mostly BlackBerry and Nokia, developed using MIDP2/J2ME which sounds like it would then run on many platforms: S60, (Open) Symbian, Android, and OpenMoko. Unfortunately I don’t imagine much of the UI code can be reused for such initiatives, but the backend should be fairly portable.

Mark Jaquith reminds us that the iPhone isn’t an open platform (further reading).

Thursday, July 24th: WordPress on iPhone has been available since Tuesday, and now the source is also available.
