Chaotic Truth did an investigation on the folks calling Sprint customers. I don't know that I agree with his ultimate conclusion, but I do think it's possible this is a phishing scam. While that may be the case, I wonder why the scam seems to affect only Sprint customers. It makes me wonder if Sprint's customer database has been hacked, if they've sold some customer names to the wrong people, or if our personal information has been compromised in some way. Only time will tell, I guess.
