Hey I just updated to wp8.1 GDR1 devprev and after the second update (which is the main one) I'm trying to continue updating( to get cellular data toggle for example) but it's just showing me this error that the server might be temporarily issued or my connection might be bad , my connection is perfect , and when I turn the preview off , it shows that my phone is updated ( not a server issue ) so what's going on?!!
