I got this from an OSNews submission on this. In a previous post on the subject, I lamented how Apple exercises near-total control over third-party developers' abilities to write applications, such as what programming language and tools they use.
Well folks, this just in from Apple itself: the requirements have been relaxed! Now, developers can use any tools and languages they want (as long as no other code is downloaded); in addition to this, Apple is being more transparent (or so it says, but we'll see about that) about its review process.
These are both huge pieces of good news for iOS developers who have been shut out of the process for reasons never fully made clear (until now). Hooray, and bravo Apple!
