We use Nokia E71's with three for mobile email + web access. Problem is the gmail app (and IMAP access to gmail via the nokia mail thing) just died the other day. When I tried to use the gmail app it would present me with this nice message:
But I knew the web connection was working as the web browser worked. To make things even more confusing when I used the inbuilt nokia mail app it would say "connecting" and then just stop. No feedback, no nothing, just dumped you back to the inbox with no new email goodness. So after digging about a bazillion different posts on forums and fiddling with the app settings and connection settings all to no avail, it finally dawned on me. Perhaps the certificates had got corrupted or they changed as part of this gmail -> mail.google.com thing? So:
menu->Settings->General->Security->Certificate Management->Trusted site certificates
I deleted anything that looked like gmail and tried again. aaah, gmail happiness again.
