There are a lot of threads where people want to use Swype and not switch to a non Swype keyboard but not have the damn phone make it impossible to type what you want. This is very EASY.
Do the following and you WILL have Swype and no predictive spelling driving you crazy.
SETTINGS/LANGUAGE AND INPUT/ now click on PREDICTIVE TEXT NOT THE SLIDER. Once in there uncheck word completion. I came from a Fascinate and this was driving me crazy, couldn't even correct the words that SWYPE was coming up with.
