Reports suggesting that Apple would be introducing its new iPhone 5 smartphone in September could have been scuppered after a report from AllThingsD’s John Paczkowski suggested the device will be unveiled one month later.

Previous reports indicated that US mobile operator AT&T had blocked employee holiday requests scheduled over the last two weeks of September, suggesting the launch of the new iPhone had been pencilled in for that period.

AllThingsD’s source said that those believing the holiday blackout was in preparation for the launch were misinformed:

“I don’t know why AT&T’s calling for all hands on deck those weeks, but it’s not for an iPhone launch.”

When asked when the iPhone 5 would launch, the source talked of an “October” unveiling, but declined to give a dedicated launch date. Other sources have said it will be late October, suggesting a holiday season push by the Cupertino-based company.
