C550 T9 Features on the C500

[Guest Pagemakers]

The C550 has 2 great T9 additional options....

1) The option to turn off the next word prediction feature when composing messages - Is there a reg tweak to do this on the 500?

2) The ability to add/remove T9 words to the custom dictionary - Is there an app available to do this on the C500 (an app that installs on the phone)?
