[jodie888]

I'd bought my xperia arc 2nd hand unlocked but after an update it had to be sent in for repair under warrenty but on return the phone is now blocked to it's orginal carrier network3 , does anyone know the sim unlock code or could i get this from network3 ? 

  Any help would be gratefully received
