"If you’re leasing an iPhone, you’ll need to connect to AT&T, T-Mobile, or Verizon when you enroll."
Damn, this is the dealbreaker for me.
Leasing an unlocked iPhone and being able to use my current $25/mo MVNO of choice (US Mobile) may have actually tempted me (I currently buy outright and then tell myself I'll sell my current phone when I upgrade, but in reality I just have iPhone graveyard at home.)
It's a little unclear; they make you select a carrier, but buried in the fine print is:
"For iPhone only: In order to lease an iPhone, you must select an eligible carrier (but you cannot use a prepaid carrier plan). A leased iPhone is always unlocked, so you can switch carriers at any time, subject to your carrier’s terms."
So it... is unlocked? I am also on US Mobile and don't want to leave it
