According to The New York Times, Motorola's upcoming revision to the ROKR E1 will not include Apple iTunes Music Stores support. Instead, the ROKR E2 will support a new subscription music service from Motorola called iRadio.
The iRadio service, will include 435 commercial-free radio channels, including genres such as Heavy Metal, Rockin' Cowboys and Angry Women. Its satellite rivals also provide specialized music channels, often without ads.
The Motorola ROKR E1 was the first cell phone to provide support for Apple's iTunes Music Store. The phone, however, was met with poor reviews. Last we heard, Motorola was revamping the ROKR to address these shortcomings. Apple iTunes support, however, appears to have been dropped with the revamp.
Motorola, however, still offers iTunes support in their recently announced RAZR V3i phone.
