Hints of iChat for iOS found in code teardown

New code found within iOS 5 suggests that Apple is considering releasing a unified iChat client for its mobile platform. RazorianFly points to a series of tweets from developer John Heaton, who found references to a variety of services, all consolidated under an IMService banner. Specifically, the code references iMessage, FaceTime, Jabber, and AIM; consolidating all those various messaging protocols under one application would substantially simplify messaging on the devices. Such a move could also lead to similar changes to iChat for Mac, which currently handles only the latter two protocols, while FaceTime is a separate app, and iMessage is currently unsupported on the Mac.
