Well i live in Australia and i managed to get f psn working again i just had to re copy the files and reboot ps3 a couple times
i used to use Charles bypass try rebooting ps3 and re copying the files back well the CA24.cer back a couple times and make sure Charles is unblocked on windows fire wall or any other fire walls same with the psn dns and make sure you have the ps3 update.txt file properly configured same with charles.config file in app data i have patcher that let me have Charles forever not as a trial and a registered patched version. If you want it ask and ill upload a copy of the patcher but f psn still working for now.
