Blackberry announced a number of Blackberry OS 7 along with three Torch smartphones earlier this month and now they've announced another three smartphones running on the new operating systems.

All of the new smartphones are in the Curve range, which seem to be more affordable than the Torch range. The three new smartphones are the Blackberry Torch 9350, 9360 and 9370. Blackberry are describing the new devices as affordable, easy to use , fully feature and socially connected.

The specification for each smartphone wasn't given in full but we do know they'll all run on Blackberry OS7 and will have a 5 mega-pixel camera, QWERTY keyboard,  WiFi and 3G connectivity and microSD  support.

They will also all have 2.44 inch screens which run at a resolution of 480*360 pixels. It seems possible that the 9350 and 9360 are built for different wireless networks (i.e. One for US and one for Europe), while the 9370 has 1GB of onboard memory compared to 512MB on the other two. All three mobiles support NFC for wireless contactless payment.

Blackberry OS 7 brings a number of improvements to any Blackberry smartphone which include a faster, easy-to-use and feature packed new web-browser. Other software includes a premium version of Docs To Go, Blackberry Balance , Blackberry Messenger and Social Feeds 2.0.

The new Blackberry Curve smartphones are launching around the world from September.
