If anyone from Whisper Systems is reading, can you please tell me how I can disassociate my number from a Cyanogenmod installed version of TextSecure in my (now formatted and sold) Nexus 4 and get it working with my no sim Nexus 5 with Google Voice/Hangouts?

Your unregistering options are best summarized here: http://support.whispersystems.org/customer/portal/articles/1...

Sadly, it's been over a year since that post and the modifications to CyanogenMod and TextSecure haven't taken: I'm unable to unregister either CM or TS, using their tools or their website.

Earlier quoted context omitted.

I'm just astonished that there's even justification for it not being an option. Bang on about easy discovery all you want, there's lots of people who don't want to give out their phone number for no good reason to some strangers.

This is nowhere nearly as simple as "you just published your phone number to TextSecure": https://whispersystems.org/blog/contact-discovery/ It is a very real security issue, too. What Matt Blaze is talking about with "extra namespaces" is a giant piece of attack surface TextSecure is avoiding.

I think that I'd be happier with social-network discovery: I can see my friends, and those of their friends whom they have shared with me; I can then ask to become friends with those whom I know, and then see their friends, and so forth. My namespace would be local to me, but I could browse my friends' namespaces as well.

You keep talking about "discovery". I don't want to be discovered. I don't want my Signal identity to be tied to any phone number.

Use other tools. There's plenty of alternatives for secure communication. The OWS apps have a specific purpose that's closely tied to how smartphones are used.

This is huge. If you have an iPhone, install Signal.

Can you elaborate more, please?

It's a cryptographically well-audited replacement to iMessage, Skype, and traditional telephony, all of which leave room for governmental and malicious meddling.
