Please keep in mind that most posters looking for help on these forums don't study engineering at MIT. They go to the store, a rep talks them into buying a handset for which he/she gets the best commission and then a happy client travels to another state/province/country and the phone is dead or there are huge roaming charges, big surprise. In case of Wind Mobile you don't need to go far, it's enough to drive 20 miles north from Toronto Airport to get into long distance roaming zone from Rogers.
The list of frequencies provided in my post looks similar to the list you will find in your phone's instruction manual or its specs on RIM's website, except that my list stresses band allocation in different countries. This is all what the average end user needs to know. I've heard about 1500 MHz WCDMA in Japan, and there are other bands, but I skipped them because they are not very common and I didn't have time to check references to avoid posting outdated information. As you obviously know, spectrum allocation changes all the time.
