I think I am correctly set up for POP3... But, how can I make sure I've set it up correctly?

When I first got 770, the gmail set up process would not allow me to finish, so I had to go to my PC and set up my account. Perhaps this is where I did it wrong? My gmail account works fine on my PC (both send and receive).

Should I open new account? I hate to have two separate gmail addresses (for 770 and PC) though. Thank you for your time.
