haha damn I was going to suggest a nandroid backup first but realized that it requires rooting.
I rooted using unrevoked 3.21 but have since found that it is safer to root using the sticky as others sugested. If you have problems or questions there are many here willing to help.
i know i know i did the unrevoled one and i did everything such as puttin the files on my SD card and all than went to a white screen that says update fail reboot

Are you able to get back to your main screen? If so, and the rooting failed I would just start over, of course using the sticky method gives you better instructions and lots of support, but I would use which ever method you feel most comfortable using. I also failed a few times trying to root but I kept at it until I was victorious!
