Looking for a dock/clock app for iPhone 4

Hey all, I just bought an iPhone 4 yesterday and I'm looking for an app. Basically what I am looking for is something similar to what my wife's droid has. When she puts her phone into her dock the screen stays on a clock at all times similar to an alarm clock. Does anyone know of any apps for the iPhone that will do something similar? I use my phone for my alarm, so if I can just put it in a dock on my nightstand and it displays a clock at all times that would be awesome. I have a feeling I am going to be out of luck on this though...

Thanks in advance everyone. I've done a lot of searching, and I can't find what I'm looking for. They people at the apple store weren't really any help either lol.

have you had a look at this? It mentions something in the FAQ about setting it so that your iPhone doesn't go in sleep mode. It's worth a look I guess...

iHome + sleep is a great free app. Search alarm clock in the app store and you'll find heaps!

I use the Clock! app from Golden Plum -- it stays on while the iPhone is plugged in. There's a $0.99 version that also lets you play songs from your iPod playlist on the iPhone as the alarm.
