In his most recent public letter on Apple.com, Steve Jobs has officially announced third-party iPhone and iPod touch applications as well as a software development kit (SDK) that will be ready by February. This is great news! Third party apps on the iPhone will catapult it to a level that other phones can only dream of. This is when the real fun begins.
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.
