Clarification Request
Just wondering....

....which cellular carrier ?? I know that carriers that use SIM cards, once you remove your SIM, your mobile # is no longer associated with the phone/device.

Keep in mind

That I'll not duplicate findings with google on this one. However I think you can use ADB to look around and delete the files that held such information. Then to overwrite them you load up apps till the memory is full. Then uninstall those apps.

Just like a HDD, this makes recovery nearly impossible. And if you are worried past that, then you might want to just take the hammer to it?

Again, the restore to factory then the usual you see noted (google that?) seems to be good enough. Only those that are a bit paranoid will want more.

--> This still doesn't answer how to wipe the information the carrier collected on you. Example?
