We just found out that the french ps3 servers are now online.
Only problem is we live in the UK so according to our source you can change the system language settings to French and you will be able to play online for the time being.
1. Head over to system settings on your ps3 xmb browser.
2. Go to language settings and change to French.
3. Restart your ps3 console
4. Sign into PSN and you should be able to play online!
Please leave a comment if you got it to work in your country apart from France obviously.
