iPhone 5 leaks are cropping up all over the place in the lead up to the expected 12 September launch.

A mockup of the upcoming iPhone has been spotted at the IFA trade show in Berlin. The device, which has a taller display, smaller dock connector, aluminium backplate, repositioned camera and a relocated headphone jack, was discovered by GSM Israel at an undisclosed case maker’s stand during the show.

The Verge got hold of the mockup, and has released a hands-on video that you can watch here.

Meanwhile, Chinese popstar Jimmy Lin has published several photos of himself with what he claims is an iPhone 5. The home screen does look a bit suspicious, though, as noted by Cnet Australia. Lin published the photos to his 13.6 million followers on Weibo, a Chinese social networking site.

Mockups of the iPhone 5 designed to be used by accessory makers have also flooded Chinese online shops. Most of the mockups sport similar designs, including the metal back, smaller dock connector and larger display expected to arrive with the sixth-generation smartphone.

It has also been reported that Apple is going to introduce a new set of headphones with its iPhone 5, which have been completely redesigned.

At present, though, there has been no official word from Apple about its next iPhone, so we’ll have to wait and see what the company will unveil in the coming months.
