Lion search shows MobileMe sequel nicknamed Castle
A code hunt by Consomac.fr on Saturday helped confirm that iCloud would be a direct sequel to MobileMe through discovering its codename. Searching through the elements of the Find My Mac feature, the French team found account migration features that would let users "complete your upgrade" from MobileMe to Castle. The name is presumed to be just a placeholder and wasn't accompanied by any clues as to features.
The framing by itself should confirm beliefs that at least the core features, such as mail, calendar, and contact sync, would make the transition over. iCloud would most likely entail a cloud media locker that would store music, photos, and videos for remote streaming to iOS devices and other copies of iTunes.
Officially, Apple has only said that a MobileMe-related project is coming for the spring launch of its datacenter in North Carolina. Most presume that to mean a launch at WWDC in June. [via MacRumors]
