I'm using an iPhone 4 with iOS 5.0.1, and have tried fixing this by resetting the keyboard, but it seems to be Apple's implemented autocorrect: why, oh why, does my phone correct "so" to "do". According to Wikipedia, "do" is the 19th most commonly used word in the English language, and "so" is number 41. Why would you want to replace one with the other?
