Help! Gmail sends, but does not receive!

Hello,

I am using Gmail right off the N8 - but it will not receive messages via pop.gmail.com, but will send via smtp.gmail.com.

The both use the same authentication - so the passoword works.  But anytime I try to sync or get emails, it prompts for the password.  Using a computer and web browser it works fine.  Using the actual mobile Gmail app it works.

I used:

for a guide - worked fine on my Nokia N95-4.

POP is enabled on my Gmail account.

Help?

But still no emails show up!

But no errors....

Anyone else's working?
