Maybe it's just my inability to type but seems like I'm having a lot harder time texting/typing on the new iPhone 4 than I had with the 3GS. Even when it catches my spelling errors it "corrects" them with words that aren't even close to what I was intending to type. Given that I make similar spelling errors all the time, just seems to me that the 3GS corrected those better than the new iPhone 4 does.
