YES!! Brilliant, that's exactly where it was and I did it and it all works now. I misread the HELP instructions. It said "
in the phone hit the options key", I incorrectly took that to mean go to Options in the Applications Menu.
Thanks so much for setting me right
Now I just have to call them and see if I can get my BB service (i.e. my emails) on this GoPhone plan I am on. Initially I wasn't going to get my emails on my handset while I am here in the US but now that I can use my 8310 rather than their crappy handset, I think I might try to.
Don't suppose anyone happens to know whether I can?
