Let me enlighten all HP users out there... correct me if i am wrong.. from my background experience... watever phones u buy out there in malaysia market.. it also depends on ur luck.. no matter its AP or Authorised or not.. if u r unlucky.. u will get a defective unit also rite? cos some Authorised r also water set just that the company take in in bulk( lets say they take in 1000 unit but declare tax 600unit n the rest is tax free) there is where they make money.. bcos they have the distributionship..so wat they do is just stick a piece of sirim and their own sticker and its few hundreds more expensive than AP.
