Best way to backup before replacement.

Hi there. I have a one month old HTC One X with AT&T, and I just noticed a line of dead pixels on my screen. I'm planning to return it and ask for an exchange. I was wondering if anyone could point me to backup apps that don't require root. From what I've read, app data backup without root is not possible, but can I backup stuff like my messages, my homescreen layouts, which apps I have installed, etc, without root? And is there any way to restore all these in one go?
