RIM is hoping that the newest version of the Blackberry OS will help grab back some of the users that have been defecting to other smartphones. RIM has announced three new Blackberry devices today and each of them are running the Blackberry OS 7 operating system. The new smartphones are also all in the Curve family.

The new phones include the Curve 9350, 9360, and 9370 smartphones. The three new devices will land in Canada this month and will hit carriers around the world starting in September. The three phones were designed with a similar look and feel and all promise a balance of ergonomics and style. The all use the Waterfall design similar to that of the new Torch smartphone according to RIM. The curved designs also have a soft-touch band to make them more comfortable to hold in the hand.

RIM also notes that the three new Curve smartphones are among the lightest smartphones ever in the Blackberry line at 99 grams each with the battery.

All three devices have the same 480x360 HVGA+ resolution screen and voice activated universal search. The voice search can also be used to search the web and with 3rd part apps. NFC is integrated into all three new Curve devices allowing the user to tap to connect to devices or authentic Blackberry accessories.

The phones also integrate social networking tightly with support for Twitter for Blackberry and Facebook right out of the box. The phones also have Social Feeds 2.0 to integrate social networks in one place. RIM also gave the new Curves the latest version of Blackberry Messenger called BBM6.

Pricing details are unknown at this time.
