Motorola comes up with own push email device

US handset maker Motorola unveiled its highly anticipated "Q" mobile phone, joining other makers in aiming for business consumers who want their email to go, an Associated Press report said.

The report said the Q handset, which had a QWERTY keyboard and ran a version of Microsoft's Windows, entered a crowded field dominated by RIM's BlackBerry and Palm's Treo smartphones.

Motorola said the Q device would be available for US carrier Verizon Wireless customers on May 31. A version running on technology compatible with Cingular Wireless would be available at the end of the year, although Motorola did not specifically name the carrier.
