as I was interested in updating my Symbian 3 or Symbian Anna phone with the Nokia Belle software along with storing information in sync between my current nokia phone,with Mozilla Firefox 11, as well as Mozilla Thunderbird 11, I made a choice for downloading nokia suite 3.3. and really it helped me a lot. I thought it would work great when I will make an connection through my corporate proxy, but this was not the case. my proxy do have authentication. I also trued with setting winhttp. Tried my proxy login in different means . I am running skype and proxy setting for skype is automatic proxy detection. So the issue remains undiscovered. So can you solve this further.
