The iPhone 5 will enter mass production in September, but only carry "slight modifications" over the iPhone 4, claims Concord Securities analyst Ming-Chi Kuo. Checks with supply chain sources are said to indicate that the phone will use a version of the A5 processor in the iPad 2, and upgrade its rear camera from 5 megapixels to 8. It will also allegedly make a switch to Qualcomm cellular baseband for both GSM and CDMA models.
