So. Not sure if anyone else is in this position, but thought it might be helpful.
I have two lines on my account. One is the old $30 SERO which my mom uses and the other was the standard $69.99 450 minutes and unlimited text/data. Went in to pick up my pre-ordered EVO at RS and during the activation process, the sprint rep asked the RS employee if I wanted to change my plan. I told him I didn't, but they said I could save $10. Being tired after not sleeping in anticipation of this device, I said no thanks again, but they pushed the issue. Finally they explained that since I had a SERO plan on my account, I was eligible for the Everything Plus 500$59 plan to replace my $69 plan. They said I would maintain my Sprint Premier status too. Thought this was pretty cool since it cancels out the $10 premium data (EVO) fee.
