Hi,
My friend has offered to swap me his brand new iPhone 4s for my 2 week old 4s as we both prefer the other phones colour (stupid i know). However, mines factory unlocked and his came from a network im not on. He THINKS because the phone is still sealed and hasnt had a sim card in it yet that there isnt a network lock on the phone, therefore my sim card should workout without fault.

Can anybody confirm if this is true?

Thanks,
Dan

Don't Swap, Because....

His information is incorrect. Even if a carrier locked iPhone has never had a sim activated in it, it will still be locked to the carrier's network. Only factory unlocked iPhones can simply swap SIMs to switch between GSM networks.

Also, if he's on Sprint or Verizon he won't be able to use the factory unlocked iPhone on either network anyway, no matter what. The unlocked iPhone can only be used on AT&T and T-Mobile, in the U.S.

Hope this helps...

Edit: Oh, right, just noticed you're not Stateside....
This information holds true for the U.K., with the exception that you can get the carriers there to unlock the iPhone by requesting it and/or paying a fee.

Why would you want to swap your unlocked phone, which is worth much more than a phone that is locked and worth much less?

To clarify, the carrier lock doesn't happen when you pop the sim in. If it's locked, it's locked out of the box, regardless of whether or not you turned it on with a sim inside yet. I would have him call and check. There are carriers that sell unlocked phones, and others that sell them locked but are willing to unlock them for you for free, or perhaps a small fee.

I don;t think the OP is clear about how carriers lock phones. He is hoping that the phone he is looking to trade for is unlocked as well. He doesn't want to trade his unlocked phone for a locked one.

If your phone is factory unlocked, and his/her/it's phone isn't factory unlocked.

Don't do the trade.
Your loss is his/her/it's gain.

The difference between locked and unlocked phones are a few hundred american monies.

I wouldn't mind swapping if his phone would have accepted my sim. I don't sell my phones after I upgrade... The girlfriend gets a free upgrade via me ;-)

I'm quite gutted it won't work tho!
Thanks for the replies guys

You are in the UK and you are receiving US centric advice. I would advice you not to give up. Why? Because essentially network locked phones are borderline anti-competitive to the point of perhaps being illegal. I would try your SIM card on your friend's phone WHILST you have the phone hooked up to your iTunes and may even have to try it a couple of times for it to work. If that doesn't work, ring the network with the two IMEI numbers and explain the situation. The network SHOULD help you unlock.

An iPhone isn't anything until it's activated - the lock status is determined by iTunes at the point of Activation (or by the device itself with iOS 5.0+)

If you take an iPhone out of the box and try and put a SIM in, the device wont work immediately. It'll tell you to connect to iTunes (or a Wi-Fi network) so that it can be activated.

When you connect it to iTunes/a Wi-Fi network, the iTunes Device Activation server will check the lock status in Apple's database and the phone will be activated - with or without a SIM lock. If Apple's database says that the phone is locked to carrier X and you're using a SIM from carrier Y then the phone wont be activated and iTunes will give you an error.

All five of the main carriers in the UK will unlock the iPhone - although there is a fee (except on O2) and there are some requirements you must meet before they'll unlock the device. Usually they'll only let the person who bought the phone unlock it (so your friend would need to do it on your behalf).

I understand all this. It is still locked out of the box, however, which is my point. One that is not locked will be able to take any sim, regardless of carrier, and activate with or without iTunes over a wifi connection. It is not iTunes which determines whether the phone is locked or not. This is predetermined prior to purchase. Itunes is able to push permanent unlock codes, however, if the carrier it was locked to allows this.

Be smart.

I am someone, from the UK who has done this- it is not complicated.

I am unsure on fees for anyone other than Vodafone or O2, but I have unlocked 2x iPhones, one that I had used on vodafone & one fresh out of the box from O2. Both were locked it appears- from the second they left dispatch, irrelevant of whether they had been activated or not.

But unlocking them, although not immediate, was simple. A simple email to the supplier (ie, Vodafone if bought with Vodafone sim etc.) and it took a week or so. If you google (Vodafone or relevant supplier) 'unlock request form', it takes you directly to the request form for completion. The registered mobile number and contact details are required- so the person who initially purchased the phone needs to do it to ensure the correct details are used- and the IMEI number, which can be found on the box or through settings>general>about>IMEI and the request is complete. I have done it with both suppliers, it was free, took about a week & the supplier then emailed to say complete. I now have 2 different iphones, using different sims ti which they were initially locked.

So in your case, you both have unlocked phones & they are worth the same. In fact if anything, you will be better off as your new (swapped) phone is newer! Result!

The retailer or supplier sets the lock status (in Apple's database) before the device is sold to the end user. The device cannot tell by itself what its lock status is - this must be obtained from Apple's servers.
