If these have been answered, I apologize. I have read every post on this thread, and if the answers were posted, I probably didn't understand them
1. Can I root my phone primarily to get rid of Sprint apps and keep running Sense?
ANSWER: Yes you can root just to get rid of the sprint apps. But please flash the recoery image just to use the nandroid backup
2. If I brick my phone, am I just screwed? Is there no way to repair or replace it other than just to buy a new one out of pocket?
ANSWER: Really hard to brick it unless you don't read carefully the how to root instructions. Also Nandroid will backup your stock rom that you have now just in case you mess up while deleting the sprint apps you can always restore.
