Question : Using POP3  in Exchange 2003 ( SBS2003 )

Helllo experts:
I need to setup a IPHONE to be able send and receive a corporate email account. I know Iphone supports POP3, In stead of setting up IMAP, I enabled POP3 on Exchange. I have made sure that POP3 is enabled under system manager->admin group->first admingroup->server->protocal. I also went into ADUC and make sure exchange property for the user's email account is POP3 enabled. I have also forwarded POP3 110 on the firewall to the exchang server.

My question is that 1: how do I enter user's credentials in Outlook when setting up a POP3 account.
                               2: Will this work with IPHONE?

Thanks
