Boy Genius is reporting a rumor about a red BlackBerry Pearl from T-Mobile being in the works. Pearl Red could be the name if T-Mobile keeps with the same naming convention as they do on the Pearl White.
BGR sources say that the Red BlackBerry Pearl is dark chrome red and and should be out in about a month as it is already in production.
BGR had a conceptual rendering of the red BlackBerry Pearl, however, it was pretty pink looking. I liked the one from BlackBerry Cool, which is also reporting on this rumor.
