So looks like he bought phone with GDR3 Preview or another non-public build. And what you mean "App switch option"? Can he share screenshot of extras+info "more info" button information? When you pressing that button you`re getting manufacturer name, mobile operator code, configuration ID, label ID (mine is 3046.0000.1329.10263 which is stock Russian Amber build, Black should be 3056.40000.1349.XXXX for us) and application version.
