Is UIDevice-Reachability approved by Apple?

I have come acros this and am trying to establish if used in a project submitted to Apple for the App Store are they liable to reject it?

Thanks

Applications liable to rejection code-wise are only those that use undocumented API. UIDevice reachability is not one of them. We have a few apps submitted to the app store using this functionality.
