iOS (jailbroken): Google’s new Maps app for iOS is pretty great, but it has one hidden feature that makes it even better. Here’s how to enable hidden topographical maps on your jailbroken iPhone.
This tweak was discovered by iOS developer Ryan Petrich, so you’ll need to enable his repository to install the tweak. Just open up Cydia and head to Manage > Sources, then add
http://rpetri.ch/repo/ as a new source. After refreshing Cydia, you should be able to find it by searching for “Topography for Google Maps” in Cydia.
Once enabled, open up Google Maps and open the drawer on the right. You should see a new “Topography” option at the bottom, which gives you a more Google Earth-eque view. We aren’t sure why Google left this disabled, but we assume there may still be a few bugs with it, so use at your own risk.
