OK first sprint and Ecare have no direct ties.. Hard to swallow or understand.. but its true. Ecare is from New Delhi .. which is why he used and "americanized" name.

Retentions are the people who keep you from canceling service by helping any situation you may have. So if its a diff phone you need tell them. I would defiantly explore this option before paying the ETF
