I "chatted" with Sony service in the US today and got this reply.
"I
truly understand, I have been researching this information for you and
yes Sony is currently working on a patch for it to isolate this issue
that occurred due to the Apple Software Update
I cannot assure you a
specific time and date, but what I can be able to do for you is provide
you the ES Department phone contact information (877) 619-7669,
operating hours: Mon – Fri, from 9:00 am to 8:00 pm ET"
I'm not in the US and was wondering if someone there wanted to try their luck and advise the result?
Cheers
Nick
