RBC Capital Markets analyst Amit Daryanani has released a new research report today citing supply chain checks as the basis for predicting a June or July launch for both the iPhone 5S and a lower-cost iPhone, in line with other recent reports. Daryanani says, however, that the lower-cost iPhone appears set to omit a Retina display. Daryanani's claim of no Retina display for the lower-cost iPhone conflicts with reports from reliable KGI Securities analyst Ming-Chi Kuo, who has claimed several times that the cheaper iPhone's 4-inch display will carry the same 326 pixels per inch seen on all Retina iPhone displays released to date. Daryanani's claims also raises suspicion because Retina displays are a long-established feature of Apple's iPhone lineup, with all the iPhone models currently offered by Apple supporting the feature. This includes the iPhone 4, which is offered for free with a two-year contract in the United States, although this new low-cost iPhone is said to be seeking to bring prices even lower to attract customers in markets where carrier subsidies are uncommon. Just yesterday, Apple announced to developers that all apps submitted to the App Store must support both Retina resolution and the larger 4-inch screen of the iPhone 5 and fifth-generation iPod touch as of May 1. Apps can, of course, also support devices such as the iPhone 3GS using non-Retina displays. Article Link: Apple's Lower-Cost iPhone to Lack Retina Display?
