As a non-sprint-related side note, I know of somebody whose AT&T
Wireless phone service was rendered completely unusable by incoming spam
via the email-to-SMS gateway. The typical rate was one message every 30
minutes, the only solution offered by customer service was to change the
phone number. Has anyone ever encountered spammers doing a dictionary
attack (emailing all 9999 phone numbers in a NXX) via email-to-SMS
gateways?
