Android Phones on "Partner Employee" Sprint Free and Clear?

[nduf]

I am on a "Sprint Free and Clear Unlimited Plan" (unlimited everything for about $30/mo.), which is described on my bill as a "Partner Employee Plan." I received this plan two years ago from a sprint retentions rep and obviously want to keep it as long as possible.

I have a Touch Pro 2 and was interested in moving up to an Android phone (Epic or possibly Nexus S). I have always thought that the TP2 was the best phone I could get on my plan, but I have seen some threads in here discussing success in upgrading some free and clear sprint employee plans to an Android phone.

These threads were from last fall and I was wondering if anyone has had recent success in upgrading an employee, 3rd party employee or "partner employee" F&C plan (ie not a regular retail F&C plan) to a 4g Android phone. If so, what number did you call, how did you do it or any other tips would be most appreciated. I have seen some discussion about an Indirect Employee Demo Plan W, is this plan still around and available?

Thank you in advance for any help!!
