Sony Ericsson Z520 / Z525

...anyway, I updated my phone's firmware from the sony website, which actually killed the camera driver so I had to send it in and get the firmware put on it there, not sure if it's the old firmware or not, anyhoo, my phone was gone for about a month and a half and my short term memory sucks, but I'm positive you could set a ringtone for blocked/restricted ID, now I can't find the option anywhere, I've looked through the user manual and I can't find it there either, anyhelp or am I just remembering wrong?
