David, thank you. Yes, I'm asking because I need one I can customize.

If you have one that?s hardcoded already and you?re trying to put in your own proxy then it?s probably locked to the provider. I have seen this before where someone will make a custom software change and make that field roll back even if you change it. Makes it more difficult to leave your provider and take your phone with you.
