Filed under: iPhoneWhenever word gets out about a potential software update, as it did for iOS 4 back in January (then called iPhone OS 4), you don't have to look far to find speculation about features or functionality the new version will include.
This is especially true for major revisions of the OS, which is ironic when you consider that developers get access to beta versions of the OS for testing purposes -- most smaller updates are kept under wraps right up until they are released.
