If you have an Android device and a braille display, the BrailleBack app from the Play Store is a must have. The app makes it possible to read and input on your Android device using the braille display.
For those of us who like to be the first to try new things, there is a beta version of BrailleBack. If you have a Google account and are a member of the Eyes-Free group, you can sign up for the beta here.
New Features in BrailleBack 0.96
Ability to input Braille using grade 2 mode for Braille tables that support it.
