Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
MobileMe to 'Castle' (iCloud?) Upgrade in Mac OS X Lion
Consomac.fr went digging in the latest Mac OS X Lion build to see what they could find. They discovered the icon and groundwork for 'Find My Mac' that seems to offer users the same location-based finding functionality as 'Find My iPhone'. More interesting, however, were strings that indicated that you would upgrade MobileMe to something called "Castle". (Image embedded above).
Click OK to open System Preferences and complete your upgrade from MobileMe to Castle.Consomac guesses that "Castle" is simply a code-name for Apple's upcoming cloud services and it will be replaced with iCloud before the final launch.
Apple is rumored to have purchased the iCloud.com domain name for $4.5 million dollars. The transaction (though not the specific amount) was confirmed by All Things D sources as well. This new evidence seems to suggest that the new service will replace MobileMe as it currently exists.
