Hello! looking for some help with getting voicemail forwarding working. I've tried the following *004*yourGVnum# on my N900. Typing out the info in the Phone App and pressing call. I get an error that says Invalid Number. I also get the same error if done in the Phone settings section. It seems that the phone or sim will not let me change this. What am I missing here? I've read others posting the same info *004*yourGVnum# and no one has reported "invalid number" error. Thanks Houz
