Yeah i think this. I use to unlock mobile phones for a living. This type if thing happens all the time with phones as it's very big business. Once Samsung or Nokia changed things it wasn't untill the next gen phones come out we seen solutions to unlock older phones.Let them turn all the channels off, Id give it 2 weeks and it will be announced the new encryption has been cracked and everything is back on including sky italia.
I still think some smarty pants has cracked it already but wont release it till sky uk fully encrypt all their channels.
I bet people in the know will have a solution.
