Phone trouble

As the day draws to a close I chat to my son Bruce on Viber he's in Melbourne and he had his iPhone stolen at New Year. So I erased my iPhone 4 and posted it to him. 

Tonight it appears that it needs to be unlocked so he can use a local sim. 

So like a good Dad I go to O2 online chat  and explain the problem. One if their gurus has it sorted in a few minutes though the process will take 72hours. 

Isn't technology wonderful...
