I've seen several posts on the forum asking for T9 support to be added. I want to add my voice to these people.
Not all of us have the dexterity or patience needed to use tiny QWERTY keys. Sony had a great T9 keyboard in the past (before they scrapped their keyboard in favour of SwiftKey no less). I've been using SwiftKey for over two years now. I've tried both Swype and regular tapping but it's still a lot of hard work to type well.
I like SwiftKey's feature packed keyboard but the one feature that's most lacking is support for the one keypad and typing style that was developed for phones. Please add it. It can't be that hard. Sony did it. And now you're Sony's default keyboard so please bring it back.
