I have xcode 3.2.2, is that the latest? Is 4.0 out

I want to get into iphone dev, I downloaded xcod开发者_如何转开发e a long time ago and my version on my mac is 3.2.2

I logged into the dev center, and I see "xcode and ios sdk 4.2"

The snowleapords download shows xcode 3.2.5 and ios sdk 4.2

Little confused, where is xcode 4.0 which I thought was released a while ago?

No, Xcode 4 has not been released yet. It's still in the developer preview stage (only available to members of the paid developer program). The current public stable version (as of this writing) is 3.2.5.

XCode 4 is still a beta. You must be a paid registered Mac developer or iOS developer to access the XCode 4 beta. It costs $100/year. The current release is 3.2.5, which includes the 4.2 SDK.
