I ordered 16gb iPhone 4 because my 3G had 8 and I use about 6-7 gb. I'm now really questioning that decision since the hd video will take up some room and this phone will be with me for 1-2 years. Anyone else buy the 16gb? I have a canon 5d mark 2 camera that shoots video. 21MP at 1920X1080p for 12 minutes is 4 gigs. So the iPhone should be a fraction of that which makes me feel better!
