I like DigitalPro by CTthemes. It is a premium theme but very cheap; only a couple bucks.
It has iPhone icons (they are mini icons on the home screen) & a hidden dock. Also has a weather/OCD slot. And you can scroll to the clock for a clock hot button.
You can find it in these forums and the CrackBerry store.

This theme was made for the Bold 9700, but if you have OS 5.0, it is compatible and should work on your Tour 9630. It works on mine.

Sorry but I'm home sick and a bit bored & restless so I'm back again with another:
GizmoFusion by CTthemes is a red color based iPhonish/Mac/Apple theme & is actually my fav of the iPhone type themes.
I happened to come across it by pure dumb luck. Here is where you can find it to check it out:
