We just got word from Stefano that Nav4All, a free navigation software package, is now supporting BlackBerry. They’ve got something set up called MyWorld which lets you share favourite locations on Google Maps, complete with pictures, and access them view the Nav4All client. On top of that, MyWorld is boasting Yellow Pages access, mapping, and friend tracking. It all sounds pretty good, just keep in mind that generally you get what you pay for. If you’re feeling adventurous, and want to give this free LBS a shot, you can download Nav4All by going to www.nav4all.com on your GPS-enabled BlackBerry.
