Here is one from Sprint for their data usage:

Specific Terms & Restrictions On Using Data Services
In addition to the rules for using all of our other Services, unless we identify the Service or Device you have selected as specifically intended for that purpose (for example, wireless routers, Data Link, etc.), you can't use our data Services: (1) with server devices or host computer applications, or other systems that drive continuous heavy traffic or data sessions; (2) as a substitute or backup for private lines or frame relay connections; or (3) for any other unintended use as we determine in our sole discretion.
We reserve the right to limit, suspend or constrain any heavy, continuous data usage that adversely impacts our network performance or hinders access to our network. If your Services include web or data access, you also can't use your Device as a modem for computers or other equipment, unless we identify the Service or Device you have selected as specifically intended for that purpose (for example, with "phone as modem" plans, Sprint Mobile Broadband card plans, wireless router plans, etc.).
Final thoughts:
All of you jerks who boast about using 50+gb of data per month are going to be the exact cause for Sprint's reasoning if they decide to invoke a data cap. Everyone who pays their premium data fee already plus their plan price should give you guys a big pat on the back for your contiuing efforts to help make us pay more in this already busted ecomony.
