Working mobileconfig for MasMovil on iOS 8 beta
Since iOS 8 beta 1 Apple has changed the APN payload method. I'm on MásMóvil operator (Orange ES) and it's a virtual one, that's why the APN must be customized in order to have a fully working 3G/4G connection. A friend told me that this also happens with Euskaltel.
I've successfully created a custom cellular payload APN that works (the official one doesn't, as it uses the deprecated method). You can download it from this gist.
This is a problem in beta 1, 2 and to the actual 3. Nothing ensures you that it will be fixed prior to the GM release, so grab this one.
