I'd be happy to help. Here is a bit about myself:
I've previously owned the blackberry 8830 world edition with Verizon Wireless and now own the Storm 9530.
I have no experience with VZ Navigator (always used google maps)
Have unlocked my bb 8830 for world sim card use once, haven't unlocked the storm.
If you want me to help, hit me up here and let me know what I can do.
<edit> just read the part about being a new bb user... if you need extensive programming, I'd probably not be the best bet
