DigiTimes offers an interesting Q&A with one of its research analysts reporting several previously undisclosed details about the development of the fourth-generation iPhone expected to be introduced early next month at Apple's Worldwide Developers Conference. One of the most interesting tidbits included in the report is a claim that Apple had a second next-generation iPhone under development that more closely resembles the iPhone 3GS, a phone which Apple has been keeping in reserve in case unforeseen difficulties with the more significantly redesigned versions seen floating around in prototypes forced Apple to fall back to manufacturing processes with which it is already familiar. In fact, it seems possible that there may even have been a third version of the next-generation iPhone floating around Apple's labs, as details found in the iPhone SDK 3.2 back in February revealed a device, presumed to be an iPhone, carrying an "N89" internal model number. The iPhone 3GS carries internal model number "N88". The report also claims that a Verizon-compatible iPhone scheduled to be produced by Pegatron instead of Apple's existing iPhone manufacturing partner Foxconn will not enter mass production until at least the second half of this year, if not 2011. Finally, the report notes that Apple did investigate the possible use of OLED screens in the next-generation iPhone, but ultimately decided against adopting the technology due to insufficient production capacity, cost, and performance issues. DigiTimes has had a spotty record in the past with a number of inaccurate product claims over the years, but does seem to have a better handle on the pulse of Apple's Asian suppliers and manufacturing partners than most other sources.
