Hi Lance, I don't know if this is too late to help you or not (but it may help someone else too). I've decided to bring my BB to Jamaica (instead of my laptop because I don't want to lug it around and worry about it). I just used this guy http://www.theblackberryguy.ca/ to unlock mine.
He has a few different options on his site, however I searched on eBay for unlock codes and got one from him for only $0.99! And it worked almost instantly, I had one little problem which was totally my fault because I missed the part where it says to not include any spaces or periods when I entered in the IMEI #, but he was VERY helpful and it was unlocked in minutes. So easy, and cheap!
