In messages (HTC Desire), when I type 'if', it automatically suggests 'of'. I don't want to turn off the word predictions because generally I find them very useful but I have no idea why it keeps wanting to change 'if' to 'of'; obviously with 'if' being such a common word, it's a real hassle to keep changing it. I wonder if when I got the phone I typed 'if' and meant 'of', so changed it... but now I can't see how to get it back. Does anyone have any ideas how I can reset the prediction? It's driving me crazy, so any help would be massively appreciated.
