Launched on September 7, 2005, in San Francisco, California, the E1 is the first phone to be integrated with Apple's iTunes music player, the next phone being the first iPhone in 2007.^[1] The phone had been widely expected, with technology sites reporting on collaborations between Motorola and Apple as far back as December 2004.

The E2 was released in January 2006. Instead of iTunes, the phone came bundled with RealPlayer, supporting a larger variety of formats. It also featured a music control panel on the left side of the phone. Users can also listen to stereo FM radio with Motorola Rokr E2. By using iRadio, FM radio programs can also be downloaded into the phone through internet, letting users listen to the radio at any time. The first public release occurred on June 22, 2006, in China.^[6][7]

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 Z6, originally known as the Rizr Z6, was released on July 7, 2007. The Z6 features Motorola's new version of the embedded Linux-based operating system, MOTOMAGX. It also supports stereo Bluetooth technology (A2DP) and features a 2-megapixel digital camera. The Z6 also supports synchronisation with Windows Media Player 11, allowing playlists and audio to be transferred to the phone's internal memory, which can in turn be transferred onto a compatible microSD memory card. The phone does not support 3G or HSDPA, relying on EDGE for data.

The Z6m is the CDMA version of the Rokr Z6. The Rokr Z6m comes with an integrated music player, 3.5 mm headset jack, stereo Bluetooth, a 512 MB MicroSD card in its respective slot, a key lock switch, and a 2-megapixel digital camera. The phone supports up to 2 GB of removable storage.

Unlike the Z6, the Z6m does not run MotoMAGX, a version of Linux, but instead runs the Binary Runtime Environment for Wireless operating system, also known as BREW.

U.S. Cellular was the first carrier to release the Rokr Z6m on October 14, 2007, alongside their Napster-to-Go service's launch.^{[citation needed]}

The E8 was released in July 2008. It features a new keypad interface called ModeShift, which automatically changes the context of the keypad depending on the current function of the device. It also features a localized touch feedback system with haptic technology that gives the feeling of real buttons, though the keyboard surface is smooth. It will sync with Microsoft Outlook, but not with Web or Mac based calendars.

Both E8 and EM30 uses the ModeShift technology and this enables the phone to switch from talk to music with one touch (special music keys light up when playing music) Coupled with in-build CrystalTalk technology (a Motorola patent), crisp and clear conversations is possible in noisy environments.

The EM30, releasing in August 2008, was the lower-end version of the E8 (see above), without the FastScroll navigation wheel and the haptics feel.

EM30 is running on LiMo Platform, a Linux-based operating system for mobile devices. It is the 22nd LiMo Handset.^[12]
