iphone app submission for iOS 6.0

Question

I have existing iphone app which is developed using XCode 4.2 and base sdk as iOS 5.0,Compiler is APPLE LLVM compiler 3.0. Now as the iOS 6 is upcoming am I supposed to (or rather ought to) rebuild this app with latest XCode and the base SDK (i.e. XCode 4.5, base sdk as iOS 6.0, Compiler :-Apple LLVM Compiler 4.1) or will I be OK submitting my upgrade with older XCode and base SDK settings? Will I be facing any issue while submitting my app built with older settings?

Answer 1

if your app works fine with iOS5 and you don't need any futures from iOS6, then leave it like this. iOS6 suppose to support the apps build with previous iOS. So, it means your app should work.
