Cingular Selling Your Number to Spanish Recordings?

Now I can’t verify this in any way; however, I have a few friends that in the last week have all received calls from a recorded message on their cell phones that is in Spanish. The common thread of these friends is that they are on Cingular. None of my Sprint PCS, Verizon, or T-Mobile friends have received such a call. Seems like Cingular may be raising the cash bar some more with possibly selling your numbers to someone? Or maybe they got hacked. Or maybe it’s just a really weird coincidence. Nah, nothings a coincidence with Cingular.
