The Desire I obtained from the local 3 Store came in a standard HTC Desire box with no special marking and just the standard HTC quick start guide. I just had a thought that it might be unlocked so I tried Orange, Vodafone and O2 PAYG SIMs. All seem to work giving me phone service but not data. The box is marked HTC Desire A8181. Am I correct in thnking it is unlocked?
