My rec is to hide yourself in your mothers womb and never leave the safety of that warm embrace oh and your virtue oh my don't forget to protect your virtue!
Honestly try acid out if your already running a hacked 4 g or earlier phone what do you have to loose? Also I have looped many a phone but never really bricked one, so I think you would have to seriously screw up to brick and life is to short to cling to an unvoided warrenty.
