If it's dispatched on Thursday then it looks unlikely my change of address will be updated in time to make it for a Friday dispatch window?

. As mine was in Prepping for shipment the only way they can change it is by informing the carrier once it has been dispatched.
If I were to get my ip6 from store on the friday and then return my (completely unopened) Apple online ip6 back to Apple would they sell it as a new iPhone or would it have to go into the 'refurb/secondary' stock?
Might just take my reservation and then return the online order back to Apple.
If I don't take my reservation I'll let anyone on here who can get to the Newcastle upon Tyne Apple store know so (if its possible) I can give them the reservation.
