I don't know when they stopped doing live streams, but I'm pretty sure they did one for the iPhone 4. I remember there was a part there (which was cut out of the one on iTunes) where Steve Jobs had a hard time getting the wifi to work. He tried to jump on AT&Ts network instead and got error messages (it was the part where he was showing off the display on the 3GS and the 4). Someone in the audience shouted out "VERIZON!" when the error message popped up. Again, this is cut from the version on iTunes but you can find it on youtube. interestingly, they left the trouble connecting to wifi, only cut the part of jumping on AT&T's network. That might be why they've stopped the live streams. I doubt it's because Cook is doing them now. People will see them anyways. I just think it's to give them a chance to edit out any mistakes or small hiccups that may occur. Thoughts?
