Any help? Googlemail notifications not coming through?

[computerboyo]

Hey there

Before I used to get a new email notification for google mail on my HTC Hero even before I would get it on my laptop, it was superquick, almost realtime.

Now I could have a new email and the notification will come 45 mins later and sometimes longer?

I had switched from 3G to 2G and I have turned off wireless locations and GPS.

But just to check none of the above should affect this should it? Maybe switching from 3G to 2G might delay it a tiny bit?

Thanks.
