Today we have another homebrew application for your PS Vita. Vita Tools version 1.6 is available for use on your PS Vita and its based on the fail0verflow tools which have been updated for use on the Vita.

You can check out notes form the author below which include what has been updated and fixed from earlier versions of Vita Tools.
