I want to re-ask this question, but for iOS 6 (existing question, based on date, is for iOS 5).
What's the best way to proceed?
The best way is to simply copy all the text and see if it needs editing - if you want to give credit to the original poster, that is nice - so paraphrase things unless you want it to be verbatum and you quote the author. For good form you should link to the old question and explain why you feel iOS 6 is different than iOS 5.
Unless you have a reason to believe the notifications are different, we should generalize the old question by an edit to say explicitly it's for iOS 5 and iOS 6.
