Apple, reportedly, has “taken steps” to ensure the iPhone 5 prototype’s safety after reports surfaced that Apple had lost yet another smartphone prototype.

The company previously lost the iPhone 5 prototype in a bar in San Francisco, and police later issued a statement that they had traced the lost device to a residence. Apple employees accompanied the police team while they raided the home.

Sergio Calderon, the homeowner, said that he had gone to the same bar but had no knowledge about the device’s loss or its whereabouts. The incident was the same as the one that happened last year with an iPhone 4 prototype.

Apple later put up a job vacancy on its Web site looking for people who could efficiently manage the risks associated with Apple's unreleased products. In addition, the new manager would also manage the security of intellectual property.

The individual will collaborate with other security managers by contributing to, and managing execution of, strategic initiatives set forth by Director, Global Security, the posting by Apple read.

Last year, when an Apple employee lost an iPhone 4 prototype at the Gourmet Haus Staudt beer garden in Redwood City, Calif., the people who found it sold the device to Gawker Media, which is parent company of Gizmodo.

Apple's iPhone 5 is rumored to be powered by the A5 dual-core processor, used in its iPad 2. A previous report also stated that Taiwan SemiConductor Manufacturing Company (TSMC) had already started a trial production of the Apple A6 line of processors that will incorporate the 3D IC technology.

Other rumored features include an 8MP camera with dual-LED flash and an edge-to-edge display. Apple, reportedly, has ordered 90 percent of its 8MP camera sensors from OmniVision. Chances of a 4G LTE-compatible iPhone 5, however, are less.

The iPhone 5 is expected to arrive sometime in the fourth quarter.
