Send My Location Tweak Will Quickly SMS Your Location
Send My Location is a new iOS tweak that will quickly SMS a Google Maps link to your location from the native Messages app.
Send My Location allows you to quickly send your current location directly from Messages.app. Indeed it replaces the Edit button by a Send Location button which will open a compose panel. Location is written as an URL that will open Maps.app.
You can download the tweak for free from the Big Boss Cydia Repository.
