Just curious if anyone else is having this problem. While in a text, I can tap the home button as many times as I want and won't get any form of response from it. The only way to get out of the text is to lock the phone and then it starts responding again. This isn't a constant problem, just something that's happened more than once in the life of my iPhone 4. And no, it's not because the home button is "clickier." No matter how firm I press it, it still doesn't respond while this is happening. Again, just kind of curious if I'm the only one noticing this.
