Nokia E62 / E61
You will get no support for the e61 from either Cingular or Nokia. Cingualr will deny that it has email capabilities and Nokia will either say it isn't capable of email or it isn't supported.
At this point, email has been generally activated on my phone number, but I have been unable to get Cingular to get me to a setup page.
Nokia is in tight with Cingular on the e62 and neither will provide assistance with the e61.
At this point I am stuck and I don't see a way to actually make email functional on this phone.
