According to anonymous sources cited by All Things Digital, Apple has indeed purchased the iCloud.com domain.

Earlier this week, GigaOM reported that Apple had allegedly purchased iCloud.com from Xcerion for the sum of $4.5 million. Apple is rumored to be announcing a major revamp to its current MobileMe cloud service at this summer’s Worldwide Developers Conference (WWDC).

Although All Things D confirms that the purchase was made, its sources declined to confirm the rumored $4.5 million purchase price. 

“Apple has indeed acquired the domain name iCloud.com from Sweden-based hybrid cloud computing outfit Xcerion. Sources in position to know confirm that Apple bought the domain as GigaOm first reported Thursday, though they declined to say whether its rumored $4.5 million price tag was accurate.”

According to Whois databases, the iCloud.com domain still shows Xcerion as the owner of the domain. Apple is probably trying to keep the purchase under wraps.
