[8125, K-JAM, P4300, MDA Vario General] naughty:
yes there is, look on the ftp for UK gprs settings CAB. Inside there is a XML file called _setup.xml that contains those, you can port that to your needs. I also am super irritated to have to enter that again and again every time, started porting it for my operator but no time to complete it yet.. someday :)

basically it looks like this fot T mobile UK, with your highly evolved brain and expert pc skills you can port it ;-)
