App developers forced to submit Retina Display screenshots
The note sent out to third-party software developers says that any future updates will not be approved by Apple unless 960x640 pixel screenshot is included, a change from the company's earlier policy which supported Retina Display screenshots but did not require them.
Previously, non-Retina Display images and apps were scaled up from their native 480x320 pixel resolution on devices that sport the high-resolution display, and many apps in the App Store have yet to support to the higher pixel count.
Currently, the only Apple products to boast the Retina Display are the iPhone 4, iPhone 4S and the fourth generation iPod touch, however speculations that the much-rumored next-generation iPad will include its own high-resolution display have been cropping up since early last year.
The iPhone 4 was the first device to use the 960x640 pixel screen, with the display being introduced to the current iteration of the iPod touch in 2010.
