Following up to my recent post, I'm now hearing additional scuttlebutt regarding the iPhone SDK release. The latest:
1. The SDK will ship on time for late February, but many features will be delayed, so this will be at best an alpha or beta release.
2. People who are in Apple's documentation department are working triple-quadruple-double-secret overtime.
3. Simulator will be there but you can also test applications directly on the hardware, via a docking cable tether.
