T-Mobile USA is now offering the BlackBerry Pearl in three more colors. This wireless carrier has also launched a new, inexpensive monthly plan just for all its BlackBerry models. Research In Motion's first smartphone debuted last fall in a black casing, and T-Mobile added a white version early this year. This carrier has now added blue, red, and light gold options.



The Pearl sells the same price -- $150 with a qualifying service plan and mail-in rebate -- no mater what color its casing.

Of course, this is the original version of this smartphone, not the updated one that's expected to hit the market this fall.

New $10 Service Option

In a related story, T-Mobile USA has introduced a new monthly wireless service plan for all its BlackBerry smartphones, not just the Pearl.

BlackBerry users now have the option to pay $9.99 a month and get unlimited BlackBerry email service. A voice plan is also required, and this service only includes email, not SMS messages or web surfing.

"For those customers initially drawn to the sleek look of the device, the new personal email service plan really lets them experience the BlackBerry Pearl?s easy-to-use email features at a compelling price,? said Leslie Grandy, Vice President of Product Development, T-Mobile USA
