I am planning to order an ipod to be delivered to my university address. All of my mail here goes to my college's central address, so I won't be able to sign for it, but if the guys in the lodge could sign for it then all would be fine. I read that people have been able to pre-sign for their packages in this thread (https://forums.macrumors.com/threads/342988/), but wanted to check if this is possible for all carriers, particularly those in the UK?
