There are only a few tabs to release to get the trim off. Take your pry tool and insert it between the lcd and silver trim. It shouldn't take much pressure as the plastic is very flexible. Then slide it down to about where the keys meet the screen and pry it out a bit. You should hear the tab pop out.
There is another tab on the opposite side in the same location, centered near where the keys and screen meet.
Lastly, you'll need to pop a couple more tabs up from under the trim at the bottom of the phone. Don't mind my photography here, I didn't have an assistant so I used a couple extra iPod tools to prop up the phone!
