I've seen it happen before and I don't post anything because I figure if nothing is changing on the phone, then it's most likely not an issue on my end. Usually when I try and send or respond to an email, and it gets stuck on "Sending..." it kills the mail thread and usually I can send within a day. Therefore I figured it's a Google issue and very temporary.
However I haven't been able to send emails all weekend. Anyone think of something in the phone that I haven't thought of that would cause this?
Of all the features that the phone offers, this is one I can't do without.
