No go on Orange for me using your IP tunneller it cant connect to update server, as soon as I turn it off tells me I have 7008 and no updates. So Zune for me cannot connect via the USAIP probably a port block issue.
P.S if I turn flight mode off it connects but no update, if i turn flight mode on again i get the cant connect error. So it is SIM based, gonna try it without a SIM in.
P.P.S No SIM and Flight Mode connects but no Update, for sure a SIM issue. Going to try a T-Mobile SIM i have lying around.
P.P.P.S Tried Voda, T-Mobile and O2 sim nada, no updates and cant connect on flight mode.
