    I'd better read up on this (before my next murder, anyway)...
    I didn't even *know* you _could_ send "encrypted" SMS/MMS.

    I'm on Android, so, what's the app that encrypts the text messages?
    Does the recipient need to be using the exact same app?

    That is interesting!

    So, say, I send a text to my friend, that I wish to make disappear
    (the text, not the friend).

    If I just need to delete the "encryption keys" to wipe out all the texts,
    then the natural next question is how.

    How would I go about finding and deleting an encryption key on a
    typical cell phone anyway?

    But there would be no point in keeping just those.
    Wrong, legally.
    Irrelevant to whether you ever allowed them
    to keep a copy after it had been delivered.
    Which says that the bulk of the US carriers don't retain
    texts at all and that even Verizon and Virgin only does so
    for DAYS which isn't relevant to the rape trial being discussed.

  4. I think truecrypt was deprecated & replaced by cryptmount, but I may be wrong.

    Varys with the technology of the phone.
    Not on an iphone in the secure wipe sense you mean.

    windows phone is not windows. they run totally different apps written
    to different apis.
    flash *can't* be secure erased due to wear leveling.
    it's possible, it's just not worth the expense most of the time.

    however, if the crime is serious enough, they absolutely will pursue
    that avenue.

    there are many such apps, with varying levels of encryption.

    usually.

    the cops only need to contact verizon or virgin and retain it within
    that time, i.e., when the rape is reported.

    you can't.

    even snapchat retains messages and the user can always take a photo of
    the phone displaying the text before it goes poof.
    the encryption keys are for your phone not other people's phones.
    erase all contents or do a full restore and it's gone, but that doesn't
    mean the data can't be obtained in other ways, even after you do the
    wipe.

    Wrong, as always.
    Completely irrelevant to whether its windows or not.
    Irrelevant to what you said.
    Wrong, as always.
    Have fun listing even a single example of where they ever have.

    That assumes the rape is reported in time and that's only
    true of Virgin anyway and its unlikely that they use Virgin.

    And assuming that there is no backdoor and no other copy of the key.

    it's not a joke.

    encryption on ios is so good that politicians and the fbi are mad and
    want apple to make it weaker.

    that's not to say it's perfect (nothing is) but it's *very* strong.

    Yes, for SMS messages.
    Yes, for SMS messages.

    However, a lot of people use "text" to mean any text message, whether
    sent via SMS or some other means.

    You can't. SMS/MMS has no ability for encryption.

    We found the answer.

    How long the "information" is saved, was listed in the very nice
    URL posted by Mr. Rod Speed.
    https://www.aclu.org/cell-phone-loc...ponse-cell-phone-company-data-retention-chart

    T-Mobile showed me how to log into https://my.t-mobile.com
    where I can see the fact that text or picture messages and even
    wi-fi connections were made, but not the content of any of those
    messages.

    So, to answer the question in the opening post, the actual content
    isn't saved by the carrier, so, that explains why the article says
    what it says about the 3 destroyed phones getting rid of the evidence.
