Hey so i'm pretty new to rooting, just did it about a week ago. I rooted to froyo and added flash. I noticed it was a bit laggy so I installed a 800mhz/wifi rom. When using setCPU, is it bad to run at "performance" permanently? Ondemand wasn't cutting it.. If I want to try another rom, should i wipe data/cache? what exactly does this function do? erase contacts and apps? I lost quite a few contacts when i first rooted because my gmail didn't automatically sync when i added new contacts. I exported to the sd card this time. I can't get any youtube video to play. I get "there was a problem while playing". and pandora also freaks out with errors. Should i reinstall froyo? Sorry for all the questions, these issues just seemed a bit vague when i researched them. thanks!
