Apple's rumored next-generation iPhone will be available for pre-order on September 9 and be released in retail stores on September 16, according to known leaker @evleaks.

"Confirmed: Pre-orders start on the 9th. You can extrapolate the launch event date from there," @evleaks said on Wednesday.

The "iPhone 7" is believed to have improved water resistance, redesigned antenna bands, an upgraded processor, and no headphone jack. It's likely Apple will keep with its two-size approach.

The details for the release of the next-generation iPhone haven't been shared by Apple.

The company is expected to hold an event during the week of September 5, where it will unveil the new handset and release iOS 10 to the masses.
