In addition to a the U.S. market, today marks the official start date for Galaxy Note 4 pre-orders in the UK. Per the company's announcement a couple of days ago, eager Note 4 buyers can now pre-order the device from Samsung's ten retail stores across the country before general sales begin on Oct. 10.
At the time of writing there doesn't appear to be any way to pre-order the device online with Samsung UK, so you'll need to drag yourself down to your nearest Samsung store to place your order.
None of the major UK carriers are taking pre-orders yet, nor is Carphone Warehouse, the sole independent high street vendor since the recent collapse of Phones4u. However the retailer will join Three and "other selected online and high street retailers" offering Galaxy Note 4 pre-orders from next Friday, Sept. 26.
