I had the first iPhone. Sales were low in part because it was locked to Cingular (then ATT when they bought Cingular). It was very much a beta device, but you could see and feel the future as soon as you used it. It certainly was more than a toy. I remember walking into my office the day after I got it and told everyone 'this changes everything'. It's not often those types of moments happen with such clarity (the one I remember prior was when I got my first 3dfx Voodoo gaming card, but I digress). The 3g version and when it went multi-carrier is when it started to really take off sales wise. Then the iPhone 4 (first retina phone) was the next big bump, followed by the first 'big' iPhone.
