Apple has announced that iOS 5 will be released next week. But, if you happen to be a developer, you can get the final release right now. Apple has updated its iOS developer site to include the latest release of iOS5.
While not everyone can get access to the download, it is now out in the wild and will most likely end up outside the developer compounds. iOS 5 will bring many new updates to the iPhone including a new notification system and iCloud integration.
