I bought my phone on ebay, poped in a SIM card, and it worked. That means its unlocked?
SIM lock: the phone will work only with a SIM from a certain operator. A phone that is not branded by an operator is never SIM-locked. So your phone is probably a standard HTC branded phone, it is not SIM-locked and you can use any SIM.
CID lock: the phone software can only be modified/upgraded with another version for the same CID. I think it stands for Country ID; this means that a phone with French Windows Mobile can only accept an upgrade of French Windows Mobile. It is probably required by Microsoft to license the software to OEMs to avoid piracy (I suppose). HTC uses the CID also to distinguish their various distribution channels, so a DOPOD branded device and an HTC branded device have different CIDs. A phone that is not locked to any country version or to any distribution channel has a SuperCID and will accept all WM software whatever the language, etc. Your phone is probably CID-locked.
