Wi-Fi geolocation is different than GPS. Wi-Fi geolocation is quicker, and more secure as it utilizes cached data from your BlackBerry. Another plus to Wi-Fi geolocation is that it tends to work when GPS is not available. There are times when GPS is not available, but you may find that you do have Wi-Fi. One caveat is that its accuracy lower than traditional GPS, but the trade off seems to be in its speed.
This is an interesting development in the the world of location-aware applications. Looks like we will be seeing even faster location fixes, and better battery life within those apps that we love.
