Yep somebody mentioned I might get a knock on the door, but apparently it is more likely to be the Police which would definitely please my Dad!
I have spoken to 02, the club and Wembley Stadium and none of them could help. The latter have details so if the person contacts Wembley then they have my details to contact me. 02 need you to pass a security check and quote the number before they do anything, they said it was unusual anyone bothered to call but to hand it to the Police (but I know once it is with the Police it will never find its way to the owner). The club said to contact Wembley.
For all I am a currently jobless following 8 months of pretty expensive backpacking, I am not going to be looking to sell or use the phone because its not mine so if people can listen/look out elsewhere that would be great, the phone will just be sat here in the mean time.
