i updated my wifes 900 and since doing so she cannot any signal at all at her work place,previous to the update she was able to get 3g on occasions and always at least 2g,now nothing at all but as soon as she leaves work normal signal resumes....
anything i can check on her phone or any suggestions??
thanks!

am in the UK btw...

You could install an app called Healthcheck it analyses all the components in the phone including cell and gives you a signal output.
