Hi. I just bought this samsung galaxy p1010 wifi only. I read that in order to get the facebook app, you need the older version so i downloaded it. It was proprly installed but the problem is whenever i log in my acct. It always says that it was incorect user/password. But when i tried to log in usijg my laptop it accepted it. I wonder what is the problem. Btw my brother can login using his acct.
