I found out about non-provisioning the hard way. It was buried in vitaly's thread, which began after I bought the phone. I would be happy if I can help other potential customers realize that MfE on this device is not the same as MfE on E71 or E51 (I have both and work great). Until NOKIA posts on their website that N900 does not provision, I will continue to warn the future potential customers of this pitfall
