And the upgrade won't mess with your SD card, at all. (If you've got something really valuable on there It wouldn't hurt to make a backup anyway ... but that's the case regardless. After all, you could lose the phone tomorrow ...)
I already have my sd card backed up, well all but one movie I think. I would just like the update to go as smoothly as possible since I'm not sure what to do if it gets messed up! Wait, I would just come here and ask for help, lol.
