Apple has made two important iPhone announcements in the past week, but both of them have gone rather unnoticed. The first is the complete revocation of the NDA (Non-Disclosure Agreement) by which iPhone developers were previously bound. Though there are still some limits on exactly what developers can disclose, Apple appears to have responded to the general hullabaloo that surrounded the original terms of the NDA.

The other big announcement is the seeding of a new build of the iPhone 2.2 software to developers. Aside from a few previously-disclosed updates, such as a reworked Safari interface, the only major functional improvements seem to be in the Maps application.

MacRumors has gotten word that the newest version of the beta for iPhone firmware 2.2 contains more than just bug fixes. The update was marked as “compatibility testing,” and we’re finally finding out just what Apple is testing the compatibility of.

Check out the new features after the break.
