Google Maps is one of my favorite, free BlackBerry applications and I'm guessing a lot of you all out there use it as well. Google, notorious for not offering any change logs has now updated Google Maps to version 4.5.1. Current users can grab the download from Google Maps mobile link and get upgraded today. If you spot any changes within the app be sure to let us know in the comments. The only thing I noticed in a brief check was that it seemed to lock onto location faster but, that could just have been my area as well.
