Boost Mobile introduces free 411 calls

Boost Mobile is sweetening its $50 monthly unlimited deal--which includes voice, messaging, and Web--with a very nice bonus. Boost Mobile customers can now make free, unlimited 411 calls. This bonus is for both the $50 unlimited customers as well as those who are on the $60 a month BlackBerry unlimited plan. Boost Mobile also announced unlimited e-mail and instant messaging in addition to the 411 service.

Boost also announced that it will be offering a version of Sprint's Samsung Rant on May 19. The sliding messaging phone will be the first of its kind on the prepaid carrier. The Rant has a slide-out QWERTY keyboard, EV-DO, a 2.0-megapixel camera, and a microSD card slot. The Rant will be available for $149.99 without a contract.
