We do know that the BlackBerry Curve 9630 will sport a full QWERTY keyboard in addition to what some might think it to be new BlackBerry OS 7, as with most of the other newer BlackBerry devices that will roll out later this year. A microUSB port is located on the side that helps juice up the handset, but everything else does seem to resemble the Curve from last year.
There is a SIM card slot within, giving rise to speculation that this could very well be a GSM device. If it were to arrive at the market at the end of this month via T-Mobile, surely an official announcement is in the pipeline? We await with bated breath.
