The Motorola MILESTONE – the European version of the similarly-uppercase DROID – is due to arrive in the UK from early December, according to retailer eXpansys.com. They're currently offering the Android-powered smartphone on pre-order with availability in 8 working days (delivered on 8th December) – and claim this is "exclusive to eXpansys in the UK".
However, the phone is also listed for pre-order from Superetrader and had previously been advertised by Clove.co.uk, although it's now been removed from their website. Motorola hasn't yet confirmed any official Milestone release for the UK.
