Hey everyone, My old iPhone 6 still has $341 that need to be paid off on JUMP for T-Mobile. If I turn it in, that's just forgiven. However, it seems like iPhones are going for more than that still on eBay. I don't know if that will be the case still post-September 25th. Has anyone here had good experiences selling their old phones and just paying off the balance to T-Mobile? Are there any fees/fines associated with that action, since it isn't how JUMP is intended to be used?
