Ok so had an issue a few weeks ago that my gmail acct was displaying 35 mails from my yahoo account and I couldnt delete from either one on the phone. So i went into settings and cleared the cache on both, problem is that now my yahoo is erased from the mail thingy on the htc wallpaper (1st to the left of home). so i am trying to add the account back it keeps saying password error wtf. what is active exchange used for, I am rooted as well. Any help?
