Okay then you can download snap. Download it from http://redlightoflove.com/snap/. Then sideload it using Sachesi or Google Chrome PlayBook plug in.
And i think it's better if you install the latest leaked OS, since android runs way faster and smoother on it. Check for the leaked OS 10.2.1.3175 thread from CB10 and install it, it's way better than the OS which is in your device right now.
That is highly unstable and is not worth installing unless don't mind playing with your phone. Have to wait till it reaches builds in 1000, since under 1000, it is for devs for bug fixes and testing purposes.
