Apple's next-generation iPhone may have a metal back and a much smaller dock connector, after purported leaked images of the upcoming smartphone were published by US Web site 9 To 5 Mac.

The photos, said to be sent to the publication by an unidentified "supply chain source", show what could be Apple's sixth-generation iPhone. The images reveal what appears to be an iPhone with a taller, 4in screen, redesigned speaker grills and a much smaller dock connector.

9 To 5 Mac says the new iPhone appears to have a metal backplate, a move away from the glass finish of the iPhone 4 and iPhone 4S models. Apple's original iPhone, which wasn't released in Australia, used a metal back before Apple altered the design to plastic on the iPhone 3G and iPhone 3GS models.

The images also show that the headphone jack, currently situated on the top left of iPhone devices, has been moved to the bottom left corner of the new iPhone. The traditional home button remains, despite rumours suggesting Apple could abolish it for future iPhone models.

According to rumours, the new iPhone will have a 4in screen with a resolution of 1136 x 640.
