If you have an iPhone or iPod touch and love the power and functionality which Google has brought back to iOS with the launch of their official Maps app, then it’s worth considering whether or not it would be worthwhile jailbreaking that device to get your hands on the latest tweak to come from Ryan Petrich. It would appear that one of the hardest working developers in the jailbreak community has discovered the hidden topography mode in the new Google Maps app for iPhone. Although Google has obviously chosen to have this feature lie dormant for now, Petrich has made it available through a tweak on his official repository.
