The rumors and leaks are beginning to gather momentum as Canadian smartphone maker Research In Motion (RIM) readies for the unveiling of its new BlackBerry 10 (BB10) OS and new smartphones at its Jan. 30 event in New York. The latest of such leaks is an image purportedly of the BlackBerry Z10 and the BlackBerry X10.

Earlier on Monday, Dec. 24, images of RIM's BlackBerry 10 full QWERTY/Touch device from the N-Series, rumored to sport the moniker BlackBerry Z10, had surfaced online. The leaked image resembled an updated version of the Bold 9900.

Now, per a MobileSyrup report, a post on Web site 4Chan shows the BlackBerry Z10 being flanked by a black BlackBerry X10 and a white QWERTY device. The white version has a different style to that of the BlackBerry X10 and could possibly be another N-Series device - the BlackBerry Dev Alpha C.

"A post on 4Chan reveals the all-touch "BlackBerry Z10″ sitting in between the full QWERTY/Touch - rumoured name is the "BlackBerry X10." There's a white version and a black version, however the white version seems to have a different style as it's missing the chrome frets. So it could be the Dev Alpha C that RIM gave 1,500 developers," reported MobileSyrup.

Some tech experts opine that the curved keyboard of the Dev Alpha C could be an indication that it is a part of RIM's BB10 R-Series.

With the RIM event barely a month away, the mystery of the new BlackBerry 10 devices will soon be solved. Till then we will have to be content with the leaks and rumors.
