Wifi maybe is worse on 4.2.2 (and above..) but more stable when it comes to connection stability..

My own experiences though!

No, it neither requires root nor unlocked bootloader
Just flash a older ftf using flashtool.

Database noob

could you please explain this steps (Just download the latest Android 4.1.2 firmware and flash using Flashtool) because it will be my first time to play around with firmwares and i dont want to f*** up my phone I want to downgrade my xperia z because from the time on i upgraded to jelly bean 4.2.2 the Phone and Contacs icons disapeared and i think its because i backed up my phone on Titanium Backup two firmwares below 4.2.2 and then after upgrading two times it restored automaticly the backup from the Phone and Contact Apps and the new update doesent support these old versions...

also the icon disappearing thing happened on my previous firmware ( before i upgraded to 4.2.2, so in my first updrage after the firmware i backed up ) always when i turned my phone off , but then i just restored it each time from Titanium Backup, with restore App+Data, and i justed wonderd why this is happening...now when i try to restore it from Titanium Backup it stucks in the loading process..
