Apple iPhone 5 arriving in late June and not the WWDC?

The majority of Apple fanboys and freaks around the globe believe that the next generation iPhone will break cover at the WWDC which is to be held in the first half of June 2011. But, the Koreans are out there to contradict this belief and they think that it will be the last week of June this year when the iPhone 5 will eventually be released. Korean news site ETNews apparently heard this at the Mobile World Congress in Spain earlier this year and that is how this source is almost certain of the iPhone 5 release in late June. For some strange reason, this source also believes that the iPhone 5 will debut in South Korea and the US at the same time, which is something that cannot be trusted. The world is so used to seeing Apple products being first introduced in the US and then elsewhere that such a change of strategy from Cupertino is indigestible. I guess the Korean source needs to do its homework right before coming up with such gossip.
