Apple has sent a message to its iOS developers stipulating that all iPhone app screenshots uploaded to iTunes Connect must support the Retina display, potentially signalling the upcoming retirement of the iPhone 3GS. Later this year, when Apple launches its sixth-generation iPhone many are executing the company to discontinue its iPhone 3GS, as it has done with the original iPhone and the iPhone 3G, in the past. This would mean that Apple’s line of iPhones would all support its high definition Retina display – an era which would be further empathised if the iPad 3 gets a super-HD display, as many suspect. Here’s Apple’s message to developers:
When you create or update your apps in iTunes Connect, you must upload screenshots that are high-resolution. We require your screenshots as high-resolution images so that your app is optimized for the Retina display.
The requirements for high-resolution images are 960 x 640, 960 x 600, 640 x 960, or 640 x 920 pixels. Images must be at least 72 dpi, in the RGB color space, and the file must be .jpeg, .jpg, .tif, .tiff, or .png. You can update your screenshot files at any time in iTunes Connect.
