I'm trying to add a new Vodafone live! APN to my list of APN's. I've checked "Connection settings -> Internet connections -> Connections", but if I click "New" there it opens a connection wizard for WiFi-connections only But I see a default "VF DE Web" APN set up there already (I guess it's from my SIM card and no, I don't want to change that but add an additional one).

Any suggestions?

u have to use fAPN application

Actually there's no way for adding APNs using system apps, but there's an interesting app called fAPN for doing that.
Install that from Extras.

Is there a reason why this has to be in Python? Surely it would be more suited to a compiled language longer term?

Thanks a lot. fAPN did the job.
