I am a former "Sprint" corporate employee and now work as a "reseller" of Sprint services. You are both correct, Corporate cannot add features that are not compatible but third parties can. Seems like a strange thing because most 3rd parties are not aware of the damage they can do to someone's bill by adding incorrect features. In your example of adding Sprint TV to a LG160, third parties can add that in the billing system. Then when the customer is using internet features and gets the next bill they can expect to see Data charged at $.003/kb because the incorrect code is on the account. Just because you can add something, doesn't mean that you should.
