All the new iOS4 APIs are included in iPhone SDK 4 so just download it and start developing.

@Cathy Connect to iTunes, "search for updates", update, done... It's offically released now.

Can anyone download the iPhone OS4 or it is only who have registered in the developers program?

Plug it in to your computer, run iTunes, choose 'Check for Upgrade' from the 'Cathy's iPhone' status page.

A:
The installation of iOS SDK 4.0 removes all SDK's before 3.2. However, you're still able to develop for your 3.0 devices.
- set Base SDK to 4.0
- set Deployment Target (Target -> Info -> Build : "iPhone OS Deployment Target" ) "to iPhone OS 3.0"
be aware of the fact that if you develop your app for 3.0, the use of API's oder Methods within API's only available from 4.0 onwards will crash your app.
the use of the "respondsToSelector" Method will let you know if a method is available on the current device that is executing your code. This enables you to make use of the new API's if your app runs on a 4.0 device whilst maintaining "backwards"-compatibility for 3.0 (or whatever OS Version you set as Deployment Target"
if([[UIApplication sharedApplication] respondsToSelector:@selector(setStatusBarHidden: withAnimation:)])

ok thats a simple one, open XCode then click Window->Organizer. connect your device, select your device from the "Devices Folder" within the Organizer. On the Right hand side you can select the Software-Version of the device.
