Oh, this isn’t going to stop until Apple’s WWDC conference in June, we’re afraid. Apple’s plans for an ambitious cloud service continue to provoke rumour and speculation. AppleInsider says that the company is using the ‘iCloud’ name internally for the service, which is expected to go beyond streaming and/or locker-based music to include photos, videos and other social features. This follows reports that Apple has bought the iCloud.com domain name for a hefty sum of money. Meanwhile, TechCrunch highlights separate reports of a new service codenamed ‘Castle’, which has been found in the latest developer preview build of the OS X Lion operating system for Macs. Castle and iCloud appear to be the same thing, but we’re guessing if one of them ends up being the commercial name for the service, it’ll be the latter.
