The mock-up, below, of the forthcoming iPhone 5 is from the website ThisIsMyNext.com.
The mock-up is by Joshua Topolsky, who, until a month ago, was the editor in chief of Engadget.
Topolsky writes, "Our sources say the new model (or at least one of the new designs in testing) looks “more like the iPod touch than the iPhone 4.” The phone will be thinner than the iPhone 4, and may have a “teardrop” shape which goes from thick to thin (something along the lines of the MacBook Air profile).
"In a sketch supplied to us by a source (on which the image above is based), the home button is doing double duty as a gesture area; this falls in line with testing we’ve seen for gestures on the iPad, and our sources say that gestures are definitely coming in a future version of iOS. The home button will likely be enlarged, but not scrapped altogether. Furthermore, we’re hearing that the screen on the device will occupy the entire (or near to it) front of the phone, meaning almost no bezel. Our source says the company is doing very “interesting things” with bonded glass technology, and has been exploring designs where the earpiece and sensors are somehow behind the screen itself, making for a device where the display is actually edge-to-edge. Regardless, the sketch we’ve seen suggests the screen will go up to 3.7-inches while keeping the current resolution, and at that size, pixel density goes from 326 to 312 (a drop of 13ppi)."
