WWDC 2011 will probably be one of the hottest tech events this year, unveiling a new generation of iPhone and whatnot. Well, this time it could take place between 5 and 9th of June, as pointed out by Appleinsider. They found a mystery event at the Moscone West, that may or may not be the Apple event.

The rest of June includes bookings for 5 different events, so this could be it, unless the Cupertino giant wants to change venue. Last year, it was all about the iOS unveiling, plus the cool FaceTime and iPhone 4. This year we guess that NFC will be a star, as well as the next-gen iPhone and maybe iOS 5.
