According to a report from Mac Otakara, a Japanese Mac blog, the iPhone 6 will feature rounded edges and a curved glass display. It could be similar to Squair Curvaceous Bumper, shown in the photo bellow, according to report. The Squair Curvaceous Bumper is a Japan-made aluminum bumper for iPhone that has rounded edges and is available on Amazon.
The iPhone 6 will feature an all-aluminum rear casing according to Mac Otakara , as opposed to having glass parts at the top and bottom of the back panel. Apple uses the glass pieces on top and bottom of the back panel to prevent blocking of signals for Wi-Fi, GPS, Bluetooth, and (potentially) NFC antennas.
All rumors point to the device having an ultra-thin design, narrower bezel, rounded edges, a durable sapphire display, Touch ID fingerprint sensor, and improved 8-megapixel camera with optical image stabalization (OIS). It is also expected for the iPhone 6 to be powered by Apple’s new A8 processor with 1GB RAM, and may feature Healthbook, TextEdit and Preview, improved Maps and more.
