One of the annoying things I have with the iPhone (and I'm sure people will disagree with me) is that if I call someone, hangup, it takes me back to contacts instead of the Home Screen. Useful if you want to make another phone call, but rarely do I make consecutive phone calls, so it is just an annoyance having to press the Home Button. Same applies for text messages - when I send a text message, I'd rather be taken to the Message Screen once its sent instead of just adding to the conversation (convenient or not, but I just read it, so why would I need to read it again?). And instead of loading the last conversation (SMS) when I hit Home then back to SMS, I'd rather it took me to the message list. Obviously it'll do that if I press back once I've sent the message. Don't get me wrong, I love my iPhone! But I'd love it if there was a work-a-round for those things.
