Though Apple is yet to unveil the iPhone 5, its fifth-generation smartphone, German carrier Deutsche Telekom is reportedly selling it.

On Monday, Bloomberg reported that it confirmed with Deutsche Telekom that beginning this week, it's subscribers may start reserving Apple's iPhone 5 smartphone.

Deutsche Telekom will reportedly hand out coupons to customers who make reservations for the device, even though the smartphone is yet to appear and there are only speculations about its release date.

Apple failed to launch the iPhone 5 this summer and is therefore under pressure to get it into the market in time for the holiday shopping season.

Apple is expected to launch a fifth-generation iPhone and an updated fourth-generation model perhaps next month.

In the U.S., Best Buy employees have been informed that preorders for the iPhone 5 will begin this week in time for a release date the first week of October.

Sprint will carry the phone for the first time when it launches, a leaked report to BGR.com states.

There have also been reports that the iPhone 5 is going into production overseas this week. If that is so, this could go right in line with the Best Buy early October release date.

Best Buy did note that Apple product introduction and launch dates are subject to change, BGR reported.
