With its glass multitouch display, fun operating system, and consumer-friendly design, the first iPhone was a breath of fresh air among the stodgy BlackBerry, Palm, and Windows Mobile handsets. The iPhone’s all-touch interface inspired multiple copycats, and changed the way we use our phones. It showed us that smartphones could work for more than just making calls or checking email--they could also be music players, gaming machines, and Internet browsers. After its original 2G (EDGE) incarnation, we saw the iPhone 3G, the iPhone 3GS, and the iPhone 4. The iPhone 5--or whatever it may be named--is rumored to launch this fall.
