BlackBerry 10's predictive keyboard gets transplanted with Octopus Keyboard for jailbroken iOS devices

RIM's latest on-screen keyboard effort may bear a passing resemblance to Swiftkey, but it also has us itching to see how the rest of the BlackBerry 10 UI will turn out. It looks like we're not the only ones, as Octopus Keyboard aims to bring the same slick prediction interface to jailbreaking iOS users. Swiping up will access suggested words depending on which letters are pressed, while the keyboard will also memorize new vocab like the iOS original. You can see how it works in real life -- and gauge whether it's worth the jailbreaking rigmarole -- in a quick walkthrough video after the break.
