I would do the things you have mentioned. it may take some detective work to find the real origin of your phone. the sim tray SHOULD provide the answer. I would want to confirm that somehow. possible with Phoenix by scanning the product code and see if it matches the sim tray? I doubt the sim tray would be changed, it is more likely that someone has changed the product code and forced another codes software that is not being accepted by the patient/N9. the sim error and wifi problem tell us that you have a a problem at least with the CMT or possibly the whole PR.....?? .bin file.
