Hi there, I just purchased a 7" Google Tablet on Kijiji. My problem is that the previous owner logged into Android Market using their username/password and it hasn't been removed. Does anyone know how to remove their email so that i can enter my own id to be able to purchase apps from the store. I realize now that i shouldn't have brought a second hand one, but i really just want it to be able to read my books. If someone can help me i'd really appreciate it. Thanx.
