HTC 8S Windows phone unlocked for $280 delivered in 10 days from Amazon.co.uk
If your looking at buying this locally they're selling for around high $300's to $400 unlocked. On contract I've seen them north of $300. The base price at Amazon shows as £208. Delivery is via Amazon Global Standard (8-10 business days) and costs £12.80. Once VAT is taken off the order cost is £186.13. Worked out to todays exchange rates that works out to be roughly $280. At that price its a bargain.
Its a UK warranty phone, so doesnt have the HTC global warranty with it, but I've not read anything good about the HTC global warranty and your buying this from Amazon, who, from experience have one of the best no quibbling warranty and returns policies you can find. The charger plus that comes with it will be UK but I've never used one. The USB cable is all you need.
