I actually have it on my iPhone. I was one of the lucky ones that saw it really quick before it got pulled. Apparently there is an issue with the exchange/contacts synchronization. So, it got pulled from the AppStore and the developers are working on it. I am sure it will be fixed soon.
It is a cool app! Great for speed dialing. And it scrolls contact faster than the built in Contact app on the iPhone!
If it wasn't for the AppStore and iTunes signing everything I would just send it to you. Oh well, they should have it fixed soon though. If I see anything, I'll post back here and give you a heads up.
