It would be nice if someone could get created and use the stock app that comes with the iPhone and make it where you could tell if the market was up or down. Really creative if you had the actual numbers of the dow jones index and was red if it was down and green if it was up. I know something similar has been done with the weather icon, like when your local area is rainy, cloudy, ect and live weather updates. We need a live stock update or 20 minutes behind is fine too.
