I have just taken an upgrade to the Kaiser from the M3100 through Orange, I also have the unlimited bundle and have been told that it will continue, I now await the arrival with reservations! Although my mobthly LR has been dropped by £5, and extra 200 mins Anynet/time added too. I use loads of Data, and this was the only option for me, if I don't get it, YES, the 7 day distance selling laws do apply, and I already have the address for return should it NOT be what I want! HOPE IT IS though.
