Draw [$2.99 - iTunes link] lets you doodle on your iPhone or iPod touch to pass the time or whip up whiteboard-style diagrams to illustrate your point, share via Twitter or email, and even challenge friend's to tic-tac-toe or homespun games via P2P.
Draw comes by way of Erica Sadun of Jailbreak, iPhone dev, and TUAW fame, and she not only knows how to make great apps, but beautifully stylized ones as well. If you want a good mix of casual productivity and just plain old-world fun on a decidedly new-world device, give Draw a go and let us know what you think.
More screenshots after the break!
