I just noticed that when I plug my bose companion speakers in to my MBP and jam, my iphone 3G is sitting my desk for over two hours and no GSM buzz berp berp berp!!!!!!! Anyone else notice this??? BTW, my battery life rocks. I was up to 1 am trying to kill it so I could calibrate, it took forever! Voice quality is way better. Very happy with my new 16GB black iphone! Worth the 4 hour wait on friday.
