John Bickerstaff here. Among other things, one of the iPhone developers for WordPress.
We’re pleased to announce that the WordPress iPhone App (OS 3.0) beta is available for testing. At this point, an XCode dev environment is necessary to compile and run the beta.
We’d love your feedback and (of course) appreciate hearing about any issues you find.
Please use SVN version 330 from Trunk as the version for testing.
Of course, for all things iPhone Dev, see http://iphone.wordpress.org/development/
