Hey all you lost iPhone5 users walking around aimlessly not knowing where to go with your Apple Maps!
A talented developer by the name of Katsumi Kishikawa has developed a simple, basic free maps app called ClassicMaps. Once you install it it will replace your Apple Maps with the environment of Google Maps app. Now bear in mind, this isn’t an official Google Maps release as this only overlays your current Apple engine such as public transportation directions and navigation – this is as close as you’ll get for now and is the best solution.
You won’t get Street View and dropping pins don’t work as well as they should but right now it’s better than what you have.
You can download the from your iTunes App Store and have it up and running in no time here – http://itunes.apple.com/ca/app/classicmap/id566173771?mt=8
