Apple today announced that they will unveil their iPhone SDK plans on March 6, including tools for third-party developers and some “exciting new features” aimed at businesses.

Apple’s invitation to the media reads:

Please join us to learn about the iPhone software roadmap, including the iPhone SDK and some exciting new enterprise features.

MacDailyNews Note: Back in October, Apple CEO Steve Jobs posted an open letter that stated in part, “Let me just say it: We want native third party applications on the iPhone, and we plan to have an SDK in developers’ hands in February.” For those keeping score, if the iPhone SDK is delivered on March 6 (not just discussed along with an announcement of a later release date), Jobs was off by six days.
