Apple has released iOS 5 Beta 6 to developers. It’s been roughly two weeks since beta 5 was seeded out, which means that things seem to be moving along quite nicely for Apple on the iOS side. As updates become more frequent, we can probably be sure that the GM (Gold Master) version will be just around the corner.
Also on the list of updates are iWork for iOS beta 2 and a new Apple TV firmware, beta 5. On the Mac side of things, OS X 10.7.2 is also ready for developers as well as iCloud for OS X Lion beta 8 and the latest build of Safari (5.1.1) which is also designed for use with iCloud.
No use in over-speculating a release date (whether it comes before or with the iPhone 5), but it seems like things are coming together.
