T-Mobile will be preparing to receive codename Malibu (or the BlackBerry Curve Touch) in late June or early July. The Curve Touch is expected to be announced at the BlackBerry World conference in May.
The Curve Touch is set to bring a touchscreen experience in a very slim style Curve form factor, which should prove interesting. The Curve Touch will be running BlackBerry OS 6.1 when it lands, but it is unknown if it will be the full version of 6 or a more compact version. It is now expected that some newer BlackBerry releases will not offer the full version 6 OS when released, or so we are hearing.
Sources tell us that AT&T announced plans to acquire T-Mobile in the U.S. will not factor into this release, but it is unknown if AT&T plans to carry the Curve Touch, as well; but we assume that it is a safe bet that they will offer it at some point.
