A few weeks ago, a file was discovered inside iOS 5 in which Apple displays the date on which it was going to release a new beta version of its operating system. Using the system present inside iOS 5, it was possible to predict the release of the beta version 6 and now we could find out information about the release of the GM version of the new operating system. Until yesterday, the date of September 18 for the possible release of iOS 5 beta 8 was displayed in that file, but Apple changed the date listing September 21 as the release day and then we could have the GM version of the new operating system available.
September 21 is a Wednesday, next Wednesday to be exact, and unfortunately Apple has not yet announced the date of the iOS 5 and iPhone 5 presentation conference, but that does not mean that it could not release a GM version of the operating system . Normally Apple releases these GM versions on the day of the conferences, but this year many traditions were "broken" so anything is possible. On the other hand, we might see iOS 5 beta 8 available on September 21 and we might have the GM version a week later, so anything is possible at Apple at the moment.
