UPDATE:
so I’ve my new Z2, its not spontaneously composted yet and its a far better phone than the iPhone 5/5s and KitKat appears far more flexible, interesting and adaptable than iOS8, I’m confident that I’ve made the right choice leaving “the walled garden” even if this new place is a snake infested app store of unregulated arse.
And yes that arsenate on the Sony support forums deserved the shortshrift as he is an obvious FanBoy (the lowest of the low) and thought he was breaking new ground in international humorist circles by, wait for it, making fun of my surname. He was lucky to get out alive to be honest.
Still, relatively happy with my Z2, although it’d be a different matter if I didn’t have faith in O2 Platinum customer services having my back!
