Google Maps for BlackBerry has been updated from version 4.4.0 to 4.5.1. There’s no changelog available and I haven’t noticed any additional features. If I had to take a wild guess, I’d say there’s some bug fixes. I know Torch users were having problems with v4.4.0 so the update would make a lot of sense if the issues with the Torch have been fixed. If you have a Torch, feel free to drop a comment below.
