Right, that's how I'm pointing out that Sprint's approach is different. They just charge all smartphone users an extra $10/month and don't care whether you tether or not. Andriod phones come with the mobile hotspot app preinstalled.

Sprint segments their users as non-smartphone vs smartphone (+$10/mo)

Other carriers segment their users as non-tethering vs tethering (+$50/mo)

AT&T is actually segmenting both, though.

Non-smartphone $15 Smartphone $25 Smartphone + tethering $45
