    Tricky question,

    I got an 3GS here wit a german t-mobile simlock (older then 2 years)
    With the ipad baseband on it (6.15?) unlocked.

    Now i want to go to 6 but what is the safest option?
    Trough the t mobile site i did a sim unlock twice but you have to update the ios before you see if it worked out.
    But im reliable on the jailbrek unlock at the moment.

    So 2 things can happen when i go to ios 6:
    Or i get the notice that he is unlocked
    or im screwed and he is still locked and there is no way back?

    How should i proceed?

    ps. there are shsh blobs of the phone

    If the carrier advised you that your phone has been placed in Apple database to be unlocked, then you can trust that.
