Three new devices purportedly from BlackBerry maker Research In Motion (RIM)'s forthcoming lineup of smartphones have appeared on the internet.

Technology blog Boy Genius Report (BGR) showed off pictures of the three handsets coupled with their rumoured specifications.

Dakota, a touchscreen smartphone with full QWERTY keyboard is said to be RIM's next flagship device.

According to BGR, the BlackBerry Dakota is designed with "the famous original Bold styling" and will measure around 10.5 mm thin.

It has a 5 MP camera with HD video recording, Near Field Communication (NFC), 3G Mobile hotspot, magnetometer, accelerometer, proximity sensor, 4GB of storage and 768MB of RAM, a 2.8-inch VGA 640 x 480 capacitive screen and will run the next version of the BlackBerry OS, 6.1.

"The BlackBerry Dakota is shaping up to be the firms best yet" said technology blog MobileCrunch but others are suggesting that may not be quite enough to impress the hard-to-please technologists and increasingly technology-savvy consumers.

"Now, these specs are definitely head and shoulders above all other BlackBerry specs," says Gizmodo, "but compared to the current crop of Androids, Windows Phone 7s, iPhones-heck, even Nokia's N-Series, the specs just aren't getting me excited."

Two other BlackBerry devices have also been pictured on the BGR website: an updated version of the company's low-price handset, the BlackBerry Curve (codenamed "Apollo") and a next generation QWERTY horizontal-slider, the BlackBerry Torch 2.

The "BlackBerry Curve finally brings up the lower-mid end of the BlackBerry lineup with very reasonable (and decent) specs for what will be an aggressively priced handset line" reports BGR. The device will get a 480 x 360 HVGA display, 5 MP camera, NFC, WiFi and GPS.

The BlackBerry Torch 2 retains its original horizontal-slider form factor whilst its insides get a power boost thanks to a new 1.2GHz processor (an increase from device's existing 600MHz processor) and various other tweaks.

BGR says the Torch 2 is set for a late Q3 release but couldn't provide further details regarding pricing and release dates for the other two handsets.
