Having had the iPhone 3G and a subscription to Sky Mobile TV for iPhone and having switched to the iPhone 4, I'm now having the problem where I cannot view the channels on the new phone. I've tried a number of times today to get through to Sky calling 08442 411 531 which is the number for their Sky ID account problems department and all I get is the message that they are busy and to call back later. I've tried to get through to this department using other contacts and it's been no use whatsoever.

I've resorted to looking for an email address to contact someone at Sky about this issue as wasting time and money in call connection charges to this number is getting me nowhere. Thinking back, I didn't look to see whether there was an option to un-pair my subscription from the old device and even if there was, it's too late now as it has already been wiped and sent into envirofone.

I have it on my Touch and I am sure Sky sent a mail advising NOT to upgrade to OS 4 at the present time as the application would not work. If they haven't updated it yet then that might well be your problem.

I believe that it has been updated now. The problem is that you are meant to have one subscription for each device. I'm no longer using the other iPhone as it's been sent off but I never done any deactivation of that. All I get on the new iPhone is a message telling me that the limit has been reached.

I don't have any experience of the iPhone but isn't it possible to deauthorise it directly from itunes?

I think Sky have their own system. That is what the iPhone would need de-authorising with.

I phoned Sky on the quoted number at around 9am yesterday morning and got straight through, no queueing at all. I was amazed!! The lady took my details and said the change could take 24 to 48 hours and I would receive an email when completed. The change over was completed and my iPhone 4 working within a couple of hours though the email took a while longer to arrive.

As far I can see the only way to do it is to ring Sky, there is no unpairing option or any otherway of contacting them to effect the change.

I managed to get through to Sky this morning and it would appear that everything has been sorted now. I called around 10am and got through first time today, unlike yesterday when I must have tried about several times throughout the day. I got a confirmation email that the device number has been reset to 0 as its one subscription per account. Tried the application and everything is fine.
