Gizomodo has a nice round up of the features announced. HomeKit sounds VERY interesting... it'll be fun to watch vendors try/not try to take advantage of that. And integrating Shazaam directly into Siri is pretty cool - but are people really hearing music that they don't recognize when they are out?
Wow...the chances of this arriving in Canada are a definite zero, considering how the Cableco's and Telco's HATE competition, especially better value competition. Lord knows how long it took us to get Wind Mobile or Mobilicity. I say bring it on.
