Apple is expected to announce its next iteration of iOS in its upcoming World Wide Developers Conference, which will kick start on June 10.

Apple has begun to decorate its Moscone Center in San Francisco, the venue for WWDC 2013, and the banner used in the process shows the number '7'. This more or less confirms that the Cupertino giant will be announcing a new version of iOS.

Moreover, the much anticipated iOS 7 recently appeared in a GFXBench database and confirmed its presence. The upcoming iOS version is expected to feature a major UI redesign with a flat new look under the leadership of Apple's Senior Vice President of Industrial Design - Jony Ive.

Apple's official WWDC 2013 app for iOS is already available and, in case you are not able to attend the event, stay tuned to our website, as we will be bringing you all the latest happenings from the developer's conference live.
