I'm not best pleased with the mobile Gmail client on my blackberry.
I successfully compose and send emails with it - but it only looks like that. In fact, I'm not successfully sending these emails and they're vanishing into the ether.
This is the biggest crime any email client could commit. I have no confidence in the application any more. I can't trust it to send my emails.
I do trust
m.gmail.comto send my emails, though, so I'll use that. The main disadvantage of the mobile web page over the mobile application is that you can't mark emails as spam. I get a lot of spam. That said; I don't think the application was successfully marking email as spam either.
Oh well. At least the mobile Google Maps application is still my friend.
