Motorola Rokr E6

Motorola Rokr E6 is a smartphone developed by Motorola first released in China on November 14, 2006, and subsequently worldwide on December 4, 2006. The Rokr E6 is a direct descendant of the E680 and the MING, sharing the same Montavista Linux operating system, Intel XScale PXA270 series processors, and the RealPlayer media player.
The E6 features a built-in FM radio. It also inherited the 2-megapixel camera with manual macro-switching and business card recognition from MING, enhanced with QR Code recognition functions. Additionally, the phone features a 3.5 mm headphone jack, allowing use of a standard-sized headphone plug.
It comes installed with Picsel Viewer with the ability to read Microsoft Office and PDF file formats.
The Rokr E6 was the third product under the ROKR name, following Rokr E1 and Rokr E2, although it was fundamentally different than those two.

Details

The phone is part of Motorola's line of phones running Linux, this one using a modified 2.4.20 kernel. This has upset some, as they broke the GPL in not releasing the kernel source code. The software is an updated version of MING, with a different file system. Most of the apps that work on the MING work on the E6, but some may not due to the file system. Normally the phone only runs on tri-band GSM networks, though some have found an exploit to get it to run on Quad Band networks and over Edge. The radio channel frequency can also be modified beyond 88 MHz to 65 MHz, and the preset number of channels can also be modified.
