iOS 5 beta 8 coming Friday, GM coming September 28, iPhone still on track for early October?

Boy Genius says, according to their trusted sources, iOS 5 beta 8 will be released this Friday, September 16, followed by the gold master (GM) on September 28, paving the way for an early October release just like TiPb heard a while back.

If September 28 is indeed the go date for the GM seed, will Apple hold their special fall event on or around that date? Apple has often used events to announce both first beta and GM seed releases in the past, and it would leave a week or two for developers to hammer on it before an iPhone 5 release on October 7 or October 14.

We'll have to wait for Apple to send out invitations to know for sure.
