The last keynote in june said that AirPlay mirroring would be on ios5 devices and now I am reading that I need a 4s?? People r saying that u need the a5 chip? That is BS. How did the developers use it prior to the 4s? And why would they mention it at the June keynote without mentioning it would only work with the new iPhone being released (4s)!?!? It was even all over their website after the June keynote!!!! Sooooo disappointed!!!! What gives??
