Apple's CEO Steve Jobs will reveal details about the company's iCloud technology at the annual Worldwide Developers conference.

The Cupertino boss will open Apple's annual Worldwide Developers conference on 6 June, when the iPad and iPhone maker is expected to pack in lots of details about its upcoming products.

And it's now clear that Apple couldn't resist adding its "i" prefix to the word "cloud", which is the tech world's idea of sexing up online storage. Microsoft is already a heavy user of the term, especially in recent television ad campaigns.

Cupertino described the iCloud tech as its "upcoming cloud services offering".

In April the company reportedly bought the iCloud.com domain name from Swedish company Xcerion for $4.5m. A separate report suggested recently that iCloud would be the next incarnation of MobileMe.
