I just contacted replacebase.co.uk about their backorder status. There is a disclaimer on their website that they get them from a US supplier and they are AT&T branded, but they should work with other country variants.
Their response is that they use suppliers from around the world. They have been monitoring all of their suppliers and haven't seen any original parts for weeks. They warned that anyone claiming to have "original" parts at the moment likely has copies from China because they are having such difficulty finding any legitimate suppliers.
