Chess.com is looking for beta-testers for an iPhone app dedicated to chess.com.  They're wanting 20 volunteers and there may still be room for several.  If you're interested in this beta-test just go to the iPhone group and check out the forum post...

I recently took the plunge and got an iPhone and it is the first piece of technology I've been actually excited about in many, many years... 

I'm sure looking forward to a dedicated chess.com app for the iPhone!
Go Erik!
