Hello! I just purchased my ipad 2 and began the set-up. I chose the correct wi-fi network, but input an incorrect password. Now I am unable to move forward. If I choose that wi-fi network, it won't prompt the password again. It seems as though it took the incorrect password and it needs to be changed. If I select my network, there is a "thinking circle" and I can't move forward on the set-up. Is there a way to go back and change the password so I can finish my set-up? Thanks in advance!
