Welcome to BlackBerry Support Forums
There are no OS 6 from Curve 8530 ,On your Curve 8530 you might have OS5. You can locate your Carrier here Carriers and if you Carrier have any lower OS version for that device model you can Install that .But OS 5 runs well so if that device is running on OS5 I don't suggest to downgrade the OS. To know the device version for device running OS 4 – 5 = Options > About > first set of numbers on the third line.
