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!

The great thing about jailbreaking (and no, it's not this) is that a lot of smart people take a look at the capabilities of the iPhone and wonder how come nobody made a (insert program here) yet? And then go and develop said program.

Case in point: A p2p client for the iPhone

iSlsk, developed by Eric Castro, is Soulseek in native app form for the iPhone. It uses the Soulseek network to let iPhone (+iPod touch) users share songs with one another. Once the songs are downloaded, iSlsk imports them into your iTunes library for seamless playback. There is a lot of promise in such a program, imagine being able to download whatever you want, whenever you want.

There are still a lot of kinks in the programming, in fact, I couldn't even manage to start a download due to some bug. But reports are floating that Wi-Fi averaged 20 Kbps while the EDGE network ran about half that. Soulseek doesn't have the install base of a Limewire and is more known for being a hot bed for indie artists but this is a great first effort into implementing a p2p client for the iPhone. Expect more updates soon.
