Nokia E62 / E61
E62 HTML Mail
The first thing I noticed is that the e-mail client doesn't support HTML mail (I am using the in-built messaging application)
The second thing I noticed is that a download of ProfiMail, which is a great HTML-handling e-mail app, could not be installed on the phone because of an "invalid certificate."
I was downloading using the Nokia Web Browser. I'll try to install it from PC tomorrow and hope that works. I too hope Cingular hasn't turned into VZW on us regarding applications from 3rd parties.
Unless there is another email app that will handle the HTML and inserted graphics as well as ProfiMail this is a deal-killer for me.
However, even though it installs, profiMail will not work properly (ie, allow for the creation of the first account).
