Ok, thanks guys.
Penguin, I was using the gmail app instead of BIS as you thought (in my recent reading I've been hearing just what you say, that most people already used BIS). I'm pretty reliant on my read/unread messages so the 4-6 hour delay is something I'll have to get used to (or you can still download the app on the net - I'm currently running gmail both ways). I do like the idea of pushing the e-mail, but since I use gmail to check my other pop3's and the frequency of the check there is variable I never found the instant arrival to be a concern for me. Of course this is just my personal e-mail, my corporate through the BES is instant.
ifonline - thanks for that info. The blackberry page for the enhanced app was just giving me 500 server errors so good to know I don't need it anyway
So, if I understand correctly the sync delay is because of gmails idle imap implementation?
