We have always said that the iPhone 5 would come in the October timeframe and it has just been confirmed by an AT&T VP. We had wrote a story earlier in the year that it was also confirmed by an AT&T rep to release in October. So this added news gives us more confidence that the iPhone 5 will release in October.
The VP specifically said “Expect things to get really, really busy in the next 35-50 days, so prepare your teams accordingly.” which would place us in early October to mid October for the iPhone 5 release. So if the iPhone 5 is slated to release October, I would expect an announcement in September from Apple or Steve Jobs himself.
