ok guys sorry for all the issues.. let me start by saying i promise i didn't alter the calculator.. only changed icon for it but NOTHING ELSE and it is working fine for me.. :/
the kernel will not OC because it's not an OC'able kernel lol it is stock with speed tweaks, flash pg or mt kernel for OC'ing
i will make an uncenter flashable soon for you guys
and battery life should be as good as ld-lg.. you just need to manually turn things off when you dont use em.. like data & wifi.. remember wifi in ON by default, there is no setup wizard for you to setup so you must go turn it off yourself and set everything up to save battery, turn brightness down, animations off or some, i deleted 99% of the background crap that usually drains battery & ram
