As we are used to, rumors are launched about the next WWDC (Apple Worlwide Developers Conference). In the serious site MacRumors, the conference would run from June 27 to July 2.
Date quite plausible, given that WWDC is given every year in June.
So as a reminder, retransmission tonight here even from 6:45 p.m. keynote announcing firmware 4, then we would see iPhone V4 announced during WWDC in June.
We discuss it on the forum.
