How to tell if your iPhone 4 is factory-unlocked

Is there anyway to tell through iTunes?

Only if you restore the OS, then if you have a factory-unlocked or carrier-unlocked phone, it'll say the device was successfully unlocked.

Will it say this even if I have the original SIM in or do I need a 'foreign' SIM inserted?

it shouldn't matter...

my iPhone is factory unlocked... so there is no "original" SIM...
all unlocked iPhones are unlocked the same way...

Hey Andrew, go buy a regular sized sim with GoPhone, activate it, go into an ATT store and tell them you lost your sim card and ask for a microsim. That's what I did. Easy.

I have an unlocked iPhone 4 (v3.2.1 b03.10.01). I know it's unlocked because I am under contract in Canada on Rogers. I've also used it in the US with my ATT GoPhone SIM.

This happened purely by luck because my jailbroken/unlocked iPhone 4 malfunctioned and I got a new one under warranty. When I took it to the US, I popped the SIM in and it magically worked!

I'm considering upgrading to iOS 4.3. Do you think if I do this I will lose my unlock status?

If it's officially unlocked (not through a hack) then upgrading the OS won't affect the lock status.

And I assume you meant to say iOS 4.2.1, not iOS 3.2.1.

Thanks, that's good to know. I won't have to bother with jailbreaking, gevey, etc.!

Yes, I did mean iOS 4.2.1.

I just did a restore, and it didn't give me any messege whether my iphone was unlocked or not..........I just popped in a different SIM, and it works fine...........because I know it was carrier unlocked, otherwise how wud one find out if he was buying it from someone claiming that its factory unlocked...........

Of course u cud always see by updating the phone and try a different SIM, but what if the phone already is running the latest firmware. I think people are already hacking the 4.3, and unlocking the iphone.

unless the seller has a reciept or is willing to meet at the Apple store.

Yup, I've never gotten the "Congratulations..." message in iTunes with my officially unlocked iPhone 4. It's still a mystery to me why some people get it and some don't.

To verify factory-unlocked status (or officially carrier-unlocked status) I would restore the phone from scratch, let iTunes activate it, and then try a few different SIMs (T-Mobile, Softbank, Vodafone, etc.) If they work you're good to go.

Doesn't matter if it's on the latest OS/baseband or not. If you do a restore, everything will get wiped and done over from scratch. It's a safe test.

When my cousin bought an iPhone 4 and was unsure, I tried my Rogers sim and it worked. I headed to the mall, paper clip in hand, walked into the Bell store and borrowed a sim from the salesperson and tried it. Worked fine.
