Just three weeks after unveiling five new BlackBerry OS 7-powered Bold and Torch handsets, RIM has today introduced three new updates to the BlackBerry Curve family aimed at the low to mid-range smartphone market; the Curve 9350, 9360 and 9370.

The smartphones are remarkably similar, launching as slim, keyboard-centric handsets that have been outfitted with an 800 MHz processor, 2.44-inch 480 x 360 display, an optical trackpad, GPS, Wi-Fi support, and a 5-megapixel camera.

As with RIM’s new Bold and Torch smartphones, the new Curve devices will support Near Field Communication (NFC) technology, as well as RIM’s stop-gap mobile operating system BlackBerry OS 7, as it prepares to roll out new QNX-powered smartphones in the coming months.

The Curve 9370 has CDMA/EVDO and Quad-Band EDGE capabilities with 1GB of in-built storage, the Curve 9360 is available on GSM networks with 512MB of storage and the Curve 9350 supports CDMA only, again shipping with 512MB RAM.

RIM says the smartphones will be available to Canadian markets later this month, rolling out to other carriers worldwide from September.
