Hi everyone, I just got a iPhone 3GS running 3.1.2..o__o it is pretty fast compared to my friends 4.1. I was wondering should I keep 3.1.2 or upgrade to 4.1? I am not sure but if I want to upgrade to 4.1 I have to do a custom firmware using sn0wbreeze. Since apple is not signing 4.1. Not entirely sure..any inputs on what I should do would be greatly appreciated!
