iPhone 5 rumors rollup in the week ending April 28: release date, ultra-thin, home button and others

New mockups present 4-inch iPhone 5

The new mockups, posted by 9to5mac, show an iPhone sporting the same aspect ratio as the one on the iPhone 4S, but a larger 4-inch screen device.

The first three mockups come from design student Daniel Bautista. The concept appears to have a stretched screen and less bezel.

The other image is from apfelpage.de, a German site that imagined a slimmer, curvier iPhone 5.

iPhone 5 home buttons will look different

According to Apple Bitch, black and white home buttons for the next iPhone are available through Chinese supplier TVC-Mall in the category of iPhone 5 replacement parts on the website.

The site writes that the buttons basically have the same design as the ones on the iPhone 4/4S, except the square piece around the button has more surface area.

These home buttons suggest that the next iPhone will be a redesigned model, different from the iPhone 4 and iPhone 4S.

Currently, the iPhone 4S has a thickness of 9.3 mm, while some Android competitors have reached a thicknesses of about 7 to 8 mm.

Hesse believes that the decision will attract new customers to the carrier.
