My Sony Ericsson Satio, when on predictive, used to put an "X" when I pressed the 9 key once. Then all of a sudden, I pressed something and now when I'm on predictive and press 9 key once, I get a "Y" and have to scroll down to select the "X". Please help? This is very annoying as I want to put an "X" as a kiss, but I have to keep changing it from a "Y" to an "X".

Any ideas? Thanks,
