This is a version of Google Maps which has been signed by Google. Signed apps contain a digital signature and a checksum. If the app is modified after it was signed it will no longer work, which helps to protect the user from malicious hacks.
More importantly to most users, if an app is unsigned many phones will constantly prompt the user to grant the app permision to connect to the internet. This makes map apps, which have to download new map tiles every time you pan or zoom, almost unusable.
This app doesn't work on Boost Mobile or Sprint phones which do not support the industry standard signatures which Google uses. It does work on many Samsung and Nokia phones from T-Mobile USA, AT&T and Tracfone.
