Update. Charge your battery up. Do an FDR and Download after you poured a nice cup of coffee and can just relax. ENJOY the little pleasure of a "new" tweak. IMO the chances of you having a problem is insignificant. I think a lot of problems are over-stated, self-inflicted or inaccurate stories (I said "a lot" NOT ALL). If you are stock (obviously you are) and you are going to have this phone for 2 years, Go ahead and have fun.
