All Things D has heard from reliable sources that the iPhone 5 will not be launching until October. It was previously thought that the iPhone 5 would launch by September at the very latest.
Sources with knowledge of the situation say reports claiming AT&T has blacked out employee vacations during the last two weeks of September in preparation for the retail debut of the next iPhone are misinformed. Instead, it’s going to be an October surprise — the month in which Apple will be launching its next generation iPhone.
All Things D is usually well connected with sources familiar with Apple products; so this could be a very reliable snippet of information. The only concrete information we have so far is the release of iOS 5 in the fall. No new iPhone would be released until iOS 5 is ready to roll. Fall does not even start until September 23, which would make October a more likely month for iPhone 5 after all.
It will be interesting to see if Apple has its usual early September iPod event; surely iPhone 5 would have to be announced either before that or at the same time!
