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?

I used to run an email to sms gateway at a previous job (where we consulted for one of india's largest mobile phone providers)

I was seeing multiple instances of this even 4..5 years ago.
