I am going to amend my previous SOLUTION post with my own theory (as opposed to the facts of the matter in my previous post.)
WinMo 6.5 automatically detects Gmail settings when you try to set up any @
gmail.com email account. Gmail is automatically set up to IMAP the account. Even if after the account is set up as an IMAP, then I go back in to change the server settings, it's an IMAP4 account type in the dropdown menu and cannot be changed.
So I cannot test the POP solution.
But, I'm thinking the problem isn't necessarily with IMAP. I think the problem is with Gmail's login authentication server as my Gmail IMAP Account keeps getting stuck on "logging in..."
