i was so hyped to pay my tmobile ETF and go to sprint with the $69.99 data/messaging plan with the EVO 4g but unfortunetly SPRINT has a special RATE PLAN for the infamous EVO 4G.take a look at this sitehttp://www.androidguys.com/2010/05/07/sprint-employees-evo-4g-training-screenshots-plenty/
There's no special rate plan for the Evo. It will work fine with a Simple Everything or Everything Data Plan. The screenshot you're referring to is training material for employees.
The "special rate plan" is a code for the Evo to be input into Sprint's system for your account -- a lot like when you purchase a Blackberry for Sprint.
The Mobile Hot Spot addon will be an additional charge, but is not required in your plan.
