All,
Apple ALWAYS releases a new OS with new iPhone hardware. They ALWAYS seed this new OS to developers for a minimum of approximately 90 prior to OS being released. That new ios then gets released along with the hardware. JUNE WWDC EQUALS SEPTEMBER/OCTOBER hardware release.
This makes sense. I doubt Apple would release iOS 6 in June/July when it hasn't even been released to developers yet.
There's a first for everything I guess, but it definitely doesn't match their previous behaviour.
I hope they at least show off iOS6, that's mainly all I care about!
