Is it bad I sometimes forget that MapQuest exists? I guess since I'm such an avid Google Maps user, I really don't find the need to use other online mapping tools.
But MapQuest isn't going away anytime soon, and with their new MapQuest 4 Mobile iPhone app, there are actually some features worth checking out. Although MapQuest 4 Mobile isn't going to replace a GPS service like Tom Tom for the iPhone, it does show nice turn-by-turn directions when you are holding your phone in landscape mode. You can also add multiple stops quite easily with its intuitive interface and swipe the screen left or right to advance to the next direction.
