Try the following. If it fails, let me know:
1. Login to Gmail - then click on "Settings".
2. Select the "Fowarding and POP" tab under "Mail Settings"
3. Select your "POP Download" option ("Enable POP for all mail" is probably the preferred option), and modify any other relevant POP settings, and then select "Save Changes".
4. Next, open "Messaging" on the Pocket PC.
5. Navigate to "Accounts" > "New Account..."
6. Step 1 requires you to enter in your email address - so enter in your full Gmail address in the format,
[email protected].
7. Step 2 involves auto-configuration, so let it do what's necessary and then proceed on to the next step which involves your user information. Here, you should enter your full name in the first text field, your full Gmail address in the user name field, and your Gmail password in the password field.
8. In Step 4, select POP3 as the account type, and type in a suitable account name (e.g. Gmail).
9. The final step requires you to specify incoming and outgoing mail servers. Incoming mail should be pop.gmail.com and outgoing mail should be set as smtp.gmail.com.
10. Before you finish, select Options - here you should tick the "Require SSL connection" box and the "Outgoing mail requires authentication" box and configure anything else according to your personal preferences.
For the first time, you may get prompted with an invalid certificate. Ignore it - it should still work. Normally, I don't use Gmail POP, but I did test it out for you, and the steps I outlined above work perfectly on my device. Hope that helps.
