Amazon announced a new generation of the Kindle on July 28, 2010. While Amazon does not officially add numbers to the end of each Kindle denoting its generation, reviewers, customers and press companies often refer to this updated Kindle as the "K3" or the "Kindle 3".

One of these, the Kindle Wi-Fi, was initially priced at US$139 / GB£111, and connects to the Internet exclusively via Wi-Fi networks. The other version, considered a replacement to the Kindle 2, was priced at US$189 / GB£152 and includes both 3G and Wi-Fi connectivity. The built-in free 3G connectivity uses the same wireless signals that cell phones use, allowing it to have download and purchase capability from any location with cell service. The new Kindle with 3G is available in two colors: classic white and graphite. Both models use the new E ink "Pearl" display, which has a higher contrast than prior displays and a faster refresh rate. However, it remains slower than traditional LCDs.
The Kindle Keyboard utilizes a Freescale i. MX353 applications processor, Freescale MC13892 power management chip, Epson EINK controller and Samsung DRAM and Flash. Other hardware changes include a larger 1,750 mAh lithium polymer battery, AnyDATA DTP-600W 3G GSM modem and Atheros AR6102G 802.11bg Wi-Fi chip.
The third-generation Kindle is 0.5 inches shorter and 0.5 inches narrower than the Kindle 2. It supports additional fonts and international Unicode characters. An experimental browser based on the popular WebKit rendering engine is included, as well as text-to-speech menu navigation. Internal memory is expanded to 4 GB, with approximately 3 GB available for user content. Battery life is advertised at up to two months of reading on a single charge with the wireless turned off.
