Will Apple accept an iOS APP build with Xcode 4.2 for iOS 5.1??

Has anyone build an iOS App on SnowLeopard 10.6.8 with Xcode 4.2 for iOS 5.1 and been accepted by Apple?

If I understand this forum post right it is possible to develop under SnowLeopard for iOS 5.1 …

…but is it also possible to release to the AppStore with that configuration??
