This should be good, think of the possiblities with a official SDK, Hopefully it will be compatible with the iPod Touch as well.
It seems as though Apple might be preparing to release the iPhone SDK to developers soon. A poster on the Blackfriars’ Marketing blog said that people need to wait for the for the Leopard Mac OS X 10.5 Leopard release later this month before you stop caring about the iPhone platform. Apple hasn’t shipped an SDK yet, not because Apple is evil, but because the iPhone is a Leopard device. The iPhone was open to third-party software from the day it was released as long as coders stuck to writing within the limited Safari environment and didn’t try to write native applications. Many hackers took this an invitation to crack the iPhone on their own terms.
