Incredible, delivery in 1 day by Fedex. The phone was described as being in very good condition, in fact it was, unbeatable value for money, I hope not to have any surprises in the future but it's a nice surprise at a very low price! The "negative" point is the protection for transport, I think that some foam or bubbles would not be refused to prevent the phone from wandering, I have not had any incident. [Updated] Noted unlocked but phone locked in Chinese firmware. The battery is not really up to scratch either with over 800 cycles already...a good deal though as I know about flashing etc but I have to recondition the device myself (battery..)
