Amazon Kindle Fire - Improve the keyboard accuracy

There is no need to be stuck with the standard Android keyboard.

Go to the Android Market (you may need to enable this first) and search for ‘Keyboard’ to see some great alternatives, many of which are more accurate and make typing much easier.
A good one is GoKeyboard.

If you see a warning saying the keyboard will collect all information (including credit cards) just ignore this. This is just a security feature that Android shows for every third-party keyboard that you install.
