The next two versions of Apple's iPhone were created under the company's late co-founder Steve Jobs, according to Mashable.

The site cites San Francisco District Attorney George Gascon who said he was told the iconic device's next two incarnations were well underway before Apple's current CEO Tim Cook took over the company.

Should Apple continue its pattern in naming its phones, the next two phones in the sequence would be the iPhone 5S and the iPhone 6.

Gascon said he came across the juicy details last week, during a meeting with Apple government liaison Michael Foulkes.

Gascon met with Foulkes because more than half of the robberies in San Francisco last year involved the theft of an iPhone. As a result, Gascon was hoping to persuade Apple to implement technology which would disable future iPhones and iPads after they are stolen and thereby render them worthless.

The district attorney argued that the implantation of such technology would make thieves less likely to even attempt to rob individuals of the popular devices.

It was following Gascon's line of questioning that Foulkes revealed the next two iPhones were designed before Cook's installation as chief executive and, as a result, kill-switch technology would not be a possibility.

Gascon said Foulkes explained that researching and producing kill-switch technology for Apple devices is a long and laborious process.

"It was very underwhelming," Gascón told The San Francisco Examiner regarding the hour-long meeting with Foulkes. "He did most of the talking. It was incredible. He would just go on and on, one subject to the next. It was hard to follow. It was almost like someone who's been trained in the art of doing a lot of talking and saying nothing."

The Examiner said that Apple did not respond to requests for comment.
