PredictiveKeyboard is one of the latest iOS jailbreak tweaks to arrive on scene, bringing auto-completion functionality to the stock keyboard on iPhone and iPod touch. As you are typing a message in the compose field in any app where the keyboard is activated, PredictiveKeyboard will try to guess the last word you are typing before you complete it.
For instance, as seen in the screenshot above, the letters “milli” were enough to prompt the following three predictions: million, millionaire and millions. For power users that are frequently using their iPhones or iPods to send text messages, emails, tweets or so forth, it’s easy to understand why this tweak is so valuable. PredictiveKeyboard by Matthias Sauppe is $2.39 on Cydia in the BigBoss repository.
