Thats it, I am considered Silver now, even though my monthly cell bill is $180 for two line shared plan.

Of course that $180 includes the Hot Spot Feature, the $10 upcharge (for whatever the reason they charge you $10 more for EVO), TEP and taxes so it doesnt qualify for Gold (but I'm still paying that amount).
I dont know how long I have been with Sprint, it should be close to ten years though. Where can i find that out?
