I have upgraded my iPhone to iOS 6, however I am currently on Xcode 4.2 (on Snow Leopard). Now I am getting this error message:

> 
> The version of iOS on “xxx xxx” does not match any of the versions of
>  iOS supported for development with this installation of the iOS SDK.
>  Please restore the device to a version of the iOS listed below, or
>  update to the latest version of the iOS.

Is it possible to restore my iPhone to older version say 5.1 or some how make my Xcode to support/recognize iOS6?
