Superuser, the preferred app to "hook into your phone's power," has at last been updated to version 3.0, bringing a huge overhaul both in terms of design and functionality.
The release of version 3.0 into the Android Market brings with it many bug fixes and new features, perhaps the most notable of these being the ability to write NFC tags, the ability to backup apps and preferences, and PIN capabilities (available with Superuser Elite).
The update also brings an automatic malware scanner, making Superuser an app that does much more than simply remember root preferences for your apps.
For a full list of changes and bug fixes, check out Superuser's full changelog. Otherwise head over to the market and get the update! For the minor fee of $3.00, you can purchase Superuser Elite, a license which gives you access to some of the app's best new features.
