So I'm using my husbands old optimus T because I didni't want to buy a new one. Anyway, although I have put in my sim card, a lot of his stuff is still on the phone. Like his calendar postings, and it's HIS facebook account not mine. Also I can't use playstore because it wants HIS gmail account and password. Is this a problem with the phone, or me? I can't figure out how to get rid of any of it and I really wanna use my stuff again. Any help???
