Call Forwarding - Unexpected response from network error

did you use the star codes to disable call forwarding?

I was getting the same error and this worked for my desire on orange:-

"Try sending ##21# which is the network code to cancel all forwarding."

Call Forwarding Problem

I have an unlocked AT&T Atrix on Orange UK running Gingerbread. As soon as you go and look at the Call Forwarding options the phone indicates that all calls are Forwarded and the Icon top left turns on, disabling 'Foward All' shows disabled for a few seconds then comes back with the 'Unexpected reponse from network' message, although calls are not actually Forwarded (can still receive calls). Old SIM card, but OK in old V3x phone. I tried with a '3' Network SIM and all works as expected, so definitely an Orange problem with Android/Atrix. I called Orange who sent some SIM updates one of which failed, called them again and they decided to send me a new SIM but this has made no difference at all.
Only way to reset the indicator and message once on, is to enter ##21# which does the job.
Just an annoying Network bug but interested if anyone knows how to get Orange (and I guess T-Mobile) to do anything about this as it seems from other research to affect several different phone makes and models.
