1262 is the last build that supported Graphics 1.0. However the core library has Facebook built in (though I’m not sure that’s true for Enterprise) which will cause your app to get rejected by Apple unless you have a valid need for the IDFA (Using ads, or FB’s publishedInstalls). Since you’re Enterprise, as long as you build with Xcode 5.1.1 you should clear the other Apple issues that’s forcing SDK users to 2189a.
