While digging into the latest developer preview of the upcoming Mac OS X Lion, Consomac is able to discover some unusual reference under “Find My Mac” app. The system string suggests that Apple is moving is cloud offering from MobileMe to a new service with the code name “Castle”. Apple is rumored to have purchased the domain name iCloud.com for $4.5 million dollars. All things point to Apple replacing MobileMe with iCloud. We will find out soon enough in June at WWDC.
