Apple plans to launch its fifth-generation iPhone this September, Bloomberg reported on Wednesday. The report contradicts information BGR exclusively reported on Tuesday suggesting that Apple may be aiming to announce and launch its next-generation iPhone in August. Most of the details in Bloomberg’s new piece are in line with countless earlier reports stating the iPhone 5 will launch in September featuring a dual-core A5 processor and an 8-megapixel camera, but one element doesn’t add up. Bloomberg says Apple is currently testing a new version of the iPad with a higher-resolution display. This, of course, is a given. But the report goes on to claim that the resolution on the new iPad Apple is testing is about one-third higher than the current iPad model. At this resolution, Apple would be forcing developers to rebuild the graphics in their apps. The resolution also wouldn’t line up with the Retina Display on Apple’s iPhone 4, which will presumably be used on the iPhone 5 as well.
