If you thought your iPhone could do anything, you're right. A new app called iGrill will even cook your dinner.

iGrill has a Bluetooth-enabled thermometer that tracks the temperature of your food, and it lets you know via cellphone when your dinner is done.

I know it sounds like a good idea, but I can't recommend it. I used it when I had a barbecue. I announced to everybody that I'd gotten a text message saying my meat was hot and juicy, and it turned out it wasn't from the grill at all.
