I have plenty of tips regarding v6 3g kak and dhbc..I'll try to write something later but can you please edit your original post to give zepp credit and link to the original xda thtead as well. Also v6 is mainly memory management...correct oom/minifrees depend on how you use the phone first..powershift is great to switch quickly before you load a memory intensive, game...also starter kit...= very first step.
Edit: I'm not saying your trying to take credit for what's not yours, just have to credit zeppelinrox and original forum...+ zepp doesnt like his files to be mirrored.
