Thought you might find it useful to know there still seems to be a problem with connecting phones like the Orange SPV M5000 and the other mobile provider equivalents. I flagged it with Orange 3rd line about 12months ago and they tested it with a couple of non-orange versions and came up with the same result...The wireless menus are locked out when selecting WPA PSK so it only seems to work if you have an authentication server... I am hoping that they passed the info on but after a recent replacement phone it appears that they may not have.
I have been hunting high and low for a fix but with no luck at present, so if you have one please let us all know.
