Apple has finally committed to a release date for the next version of its mobile OS. iOS 5 will be released on October 12th (US time, which likely translates to early morning October 13th for Australians).
If you can't wait eight more days and don't have a developer account, get iOS 5's best features right now (jailbreaking often required). But the wait won't be that long. iOS 5 will be officially available next week, and hopefully developers will see a golden master release even sooner.
