Not receiving emails automatically

[Guest Godfather]

Has anyone had a problem with getting emails automatically? I setup my email account (pop3) on my SMT5600 and I set it to check for new email every 15 minutes. But it doesn't check at all. The only I can receive email is if I do it manually by clicking send/receive. What's the point in automatic download if it doesn't work??

Also I have heard a lot about the new Windows Mobile 5.0. Is that available for the SMT5600 somewhere, wouldn't mind downloading it or buying it to upgrade my smartphone.

Thanks!
