On Apple's order page last night, the T-Mobile version was said to be unlocked. Today, that's a different story. Even so, perhaps, there was an omission one way or another. No one seems certain whether the T-Mobile version of the new iPhones, 5c or 5s, is unlocked at this time.
It makes sense that the T-Mobile version would be locked into its network. However, if the iPhone is bought at a full price, it should be unlocked no matter what. However, it appears that T-Mobile is looking to get users to sign up for service.
What also adding to my confusion on this issue is that on my iPhone, the order confirmations for my T-Mobile iPhones specifically say "unlocked". But when I sign into my account online, the "unlocked" part is missing.
Also, the "unlocked" designation is missing when I checked on the order on my iPhone Apple store app.
However, a few folks who have managed to get their hands on a T-Mobile version did confirm that these phones work with the AT&T sim cards.
The point I'm trying to make here is really about how the locking process and philosophy doesn't work anymore today. Even with T-Mobile's more consumer friendly plans and device payment plans, if you buy a phone that you're still making payments on, you are locked into T-Mobile's service. Makes no sense at all.
And that is likely at the root of this Apple and T-Mobile confusion concerning the 2013 iPhones. And why should T-Mobile's iPhones be specially locked into T-Mobile when AT&T and Verizon's versions are both unlocked.
How do I know that? Because my Verizon iPhone 5 last year came unlocked.
