Motorola Rokr

The Motorola Rokr (, styled ROKR) is a series of mobile phones from Motorola, part of a 4LTR line developed before the spin out of Motorola Mobility. Rokr models were released starting in September 2005 and continuing into 2009. They were notable for incorporating support of media player features.

The E1 is the first phone to be integrated with Apple Inc.'s iTunes music player. It was launched on September 7, 2005 in San Francisco, California. The phone had been widely expected, with technology sites reporting on collaborations between Motorola and Apple as far back as December 2004.

Description and acceptance

The Rokr E1 is a re-badged Motorola E398 candybar style phone (it was originally called the E790) with Apple-licensed technology to play back music purchased from the iTunes Music Store. It features a music player with an interface similar to that of Apple's iPod music players. Since hardware on Motorola E398 and Rokr E1 phones are the same, it is possible to Crossflash Motorola Rokr E1 firmware to Motorola E398 using phone flashing software like Flash & backup.

While the phone is equipped with an upgradeable 512 MB microSD memory card (Max. usable memory 1 GB), it is restricted by its firmware to allow only 100 songs to be loaded at any time.[1] The limit hurt the Rokr's appeal. Many users also discovered that transferring music to the phone was slow compared to dedicated players, due to lack of support for Hi-Speed USB, and there was also no wireless transfer.[2] The Rokr was also criticized for being too much like the preceding E398. As a result, the Rokr E1 sold below expectations despite a high-profile marketing campaign.[3]

Relations between Motorola and Apple were also strained because the latter unveiled the iPod nano at the same time, and Motorola CEO Ed Zander later accused Apple of purposely undercutting the Rokr.[4]

The Rokr E1 was replaced by the E2 (see below), which lacked iTunes support and was superseded by the iTunes-enabled SLVR L7.

By using iRadio, FM radio programs can also be downloaded into the phone through internet, letting users listen to the radio at anytime. The first public release occurred on June 22, 2006 in China.[5][6]

• 3.5 mm Stereo/Mic Jack
Enhanced Mini USB

The E6 was 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 instead of the iTunes player installed on the first Rokr phone. The E6 features a built-in FM radio, (but no radio recording). 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 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.[7] The software is an updated version of MING (Motorola A1200), 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.[8] The radio channel frequency can also be modified beyond 88 MHz to 65 MHz, and the preset number of channels can also be modified.

Technical information

When connected to a computer via USB and the connection type is set to "Modem/COM", the phone acts like a USB serial peripheral, allowing Motorola Phone AT Commands to be sent. In this mode, sending "AT+MODE=8" will put the phone into a different state, in which it no longer accepts AT commands but its P2K05 functionality is accessible.
