Implications may be ambiguous
Several more differences have been spotted in beta 4 of the iPhone 3.2 SDK, currently available only to developers. Significant may be multiple references to multitasking, such as a code comment discussing a "multitasking dialog box." While multitasking is already possible in a limited sense on iPhones and iPods, several reports have suggested that Apple intends to extend the option to third-party apps.
At the same time, Apple appears to have removed elements connected with video calls, including icons. The change comes roughly in parallel with UK carrier O2 adding and removing video calls as an option on iPhone plans. Because of a lack of surrounding evidence, it remains to be discovered if the video references were a slip of future plans, or traces of a feature that been temporarily or permanently axed.
