DUN with unlocked e61 on AT&T
 

Has anyone out there managed to get their N800 online using dial-up netowrking (DUN) and an unlocked Nokia e61 smartphone? I just cannot make it work. I've been able to use a Cingular 2125 WM smartphone easily. I can pair my N800 with my e61, but it will not go online. Suggestions...?
