Further digging into the code of the newly released iOS 4.3 beta has revealed a new MobileMe feature, as well as device keys for unannounced products. Mac Rumors reports that settings for a new feature called “Find My Friends” has been found. The strings appear to be associated with the Settings app and are related to MobileMe, suggesting Apple is planning to launch a MobileMe-based competitor to location-based services like Loopt and Google Latitude. Engadget, meanwhile, has discovered device keys for two next-generation iPhones—labeled iPhone4,1 and iPhone 4,2—as well as three next-generation iPads, labeled iPad2,1, iPad2,2, and iPad2,3. The article speculates that the new iPhone keys are for CDMA and GSM variants of the fifth-generation iPhone, while the iPad keys include CDMA and GSM variants of the iPad 3G, along with a Wi-Fi-only second-generation unit.
