Danger Hiptop 2 / Sidekick II

I managed to set up my Gmail POP account on the SKII with minimal difficulty, but now I am having a minor problem with it. There seems to be a delay of anywhere from 1-10 minutes between receiving an email to my Gmail account, and it registering on the SKII. If I press Menu-U, it fetches the email with no problem. I was just wondering if there's any way to get rid of this lag, and have the email sent directly to the SKII as soon as it is received, as in the case of my Tmail account? (I realize that this is probably just a fact of POP forwarding, but still, it's annoying.) Thanks for any help.
