iOS frameworks not listing in my XCode 4

I have upgraded my XCode to latest version. While I am trying to add new frameworks to my project from "Link Binary with L开发者_开发知识库ibraries" option, it is not listing some frameworks.(say, storekit). Please help me to solve the issue.

Thank you in advance.

Issue got fixed. I changed the Base SDK to iOS 4.3. It was Mac OS X 10.6 in Build Settings.
