If the latest rumors hold true, a new iPhone will be unveiled mid-September, Mashable said.

A report by iMore indicated that the next-generation of the popular handset would be announced on Sept. 12 along with an updated iPod Nano, and that both would be hitting retail locations on Sept. 21. That rumor has since been bolstered by reports from by a number of sources, including Reuters and Bloomberg.

AllThingsD also confirmed that the event would be held the week of Sept. 9 – with Wednesday Sept. 12 being the likely day of the event –- and took the investigation a bit further by looking into Apple’s recent prepayment for inventory components.

A recent spike in the company’s prepayment for inventory components indicates it’s ramping up for some sort of product release or releases soon.

The iPhone 4S was released on Oct. 4, 2011, making a late September or early October release — based on history alone — seem likely.

The huge spike in components is the highest Apple has seen in four years, which may indicate that it has something else –- an iPad Mini –- up its sleeve in addition to a new iPhone and iPod Nano.

In typical Apple fashion, the company has been silent on what we can expect. Leaked parts for the iPhone 5, or perhaps just “iPhone” suggest that the next generation of the handset will have a larger screen, faster processor, and LTE connectivity amongst other features.
