Research In Motion’s BlackBerry Pearl 9100/9105 smartphones made an appearance on the FCC earlier this month with support for GSM 850/1900, and WCDMA bands II and V.  Today, RIM passed new versions of the Pearl 9100/9105 through the FCC, this time with support for the AWS 1700 WCDMA band.  This is a good sign for T-Mobile users in the United States, since the carrier relies on AWS for its 3G service.

Buyers of the Pearl 9100/9105 will have a choice between 20, and 14 key layouts (above left and right).  We don’t have a firm release date for the new Pearls yet, but you can sign up for updates from RIM here.
