The indictment at https://www.justice.gov/usao-wdwa/press-release/file/1191031/download https://www.justice.gov/usao-wdwa/press-release/file/1191031... mentions that they worked with brick and mortar stores that do phone unlocking. I wonder how many of these were stolen phones? Otherwise, it seems like a big number of customers just walking away from their bills.
