I really like your phones and I have been using them for about 10 years, but please understand that WPA2-PSK keys can be up to 64 hexdigits long, not 63.
Please fix this issue on the Nokia E51 phone and any other phones on which this might be the same.
Also, please, don't suggest that I should persuade all the admins that use 64 digits long keys to change them and change every client that already uses such a key, just to allow a phone to use the APs they admin.
P.S.: Could somebody confirm/inform that the same issue affects the Nokia E71?
Update: The bug was confirmed for E51, E65, E66, E71 devices. I sent a report to the support for Nokia about this.
