The Kindle Keyboard is close to five years old and Amazon is still supporting it. The Seattle based company has just issued a new firmware update that seeks to resolve a security issue with the internet browser.
The vulnerability with the internet browser stems from accessing online content utilizing the 3G connection. Modern websites often have heavier security credentials when it comes to accessing email or using the login forms. The Kindle Keyboard had used an antiquated version of security, which resulted in this e-reader getting locked out and not being able to connect to certain sites.
The very small update that is currently available resolves this issue, the exact version number is 3.4.1. If you are having problems connecting to the internet I would recommend you download the firmware update manually. It can sometimes takes months for updates to hit all devices, because Amazon does it in a staggered release, so millions of people aren’t doing it all at once.
The Kindle Keyboard was the last Amazon branded e-reader that used 3G to access the internet, all subsequent models use WIFI.
