According to Garrett Smith, Nuvio recently sent a letter to Linksys (Cisco) asking if they will unlock the Linksys devices that were being managed by Sunrocket. We all know by now has bit the dust. Garrett, who is involved with VoIP Supply, which sells Linksys gear should know better.

It may not be possible for Linksys to comply with such a request, even if they wanted to. When a Linksys device is locked in the factory to a specific provider, what that means is that certain default settings are burned into non-volatile memory. This means that even if the end user were to somehow reset the device to factory settings, the device would be difficult or, if done properly, impossible for the device to be used with any other service provider.

I have no specific knowledge of how Sunrocket had their Linksys devices configured, but I do know what's possible based on a few years of experience diving deep into the Linksys (formerly Sipura) devices. If anyone knows differently, please leave a comment.
