Confirming months of speculation, Apple has announced that it will be debuting its “iCloud” service along with the next releases of iOS and Mac OS at the Apple Worldwide Developers Conference next Monday, June 6, in California.

Also confirmed is that Steve Jobs will be delivering the keynote for the conference. Jobs has been on a greatly reduced work regimen lately as he focuses on his health.

While Apple isn’t saying anything about iCloud other than to reference it as Apple’s “upcoming cloud services offering,” the consensus is that it will offer some sort of music locker service tied to the company’s wildly popular iTunes product.

It could also feature access to TV shows and movies, which would put Apple and Google on a closer competitive footing than they have ever been before. Google announced it’s own cloud-based services earlier this month, promising access to music and movies on any internet-connected device.

Update: Well it seems Apple just can’t contain its excitement around new products. Instead of waiting for the WWDC – mere days away – the company has chosen to release the iPhone/iPod Touch versions of the iWork suite of apps today. Keynote, Pages and Numbers are the three apps that comprise the iWork suite and are all now compatible with the smaller-screen iDevices.

Given that WWDC is primarily focused on iOS and MacOS, you would think this update of the iWork apps might have made ideal fodder for Steve Jobs’ keynote speech. This advance release suggests that he will have a substantial amount to say on the larger operating systems and iCloud, and likely felt that this announcement would make the presentation too long.
