Upgrade to B572 and I can help you by steb by step to have all juise from this rom
till now cm and aurora must go for a smoke with bad experience
i hope these modified roms (cm miui and aurora) sometime will be beter then hard tweaked stock
but for now I will stuck on stock b572
aurora have some tweaks to increase quadrant scores but for over experiece it's not the best rom for every day use (it's my own opinion).
