Hello,
I've just installed iPhone SDK 4.0 and it appears that the previous version of SDK has vanished from my system. I was looking for any links to download the previous version of iPhone SDK to download, but I cannot find anything.
Any ideas where I could download it?
Any new submission or update to appstore must be on IOS 4. The older IPhone sdk's are no more available for download at http://developer.apple.com/. If you think that you still need old version (for example: to run some old example), then try searching for xcode in the torrent sites. You can find there almost any version (at own risk!)
