How do i know that my iPhone 4s is unlocked because i want to upgrade it from 5.0.1 to 5.1.1

an iPhone 4s is given to me as a present. how do i upgrade it from version 5.0.1 to 5.1.1 without it being locked. how do i know it an unlocked iPhone?

If the iPhone is "locked" that simply means that you can only use it with the Wireless Mobile Carrier that it's locked to, such as AT&T or whomever.  But you can always update the version of iOS you are running, so go ahead and update to 5.1.1.  That will not hurt anything.
Hope this helps

  • How do i know that my iphone was factory unlocked or not

    i have my iphone 4s with AT&T carrier, EMIE # 012937008631144

    ONly the carrier that the phone is locked to can unlock the phone.
    Did you ask AT&T to unlock your phone and if they did, did you restore it using itunes?

    How could i know that my iphone 4s are unlocked completed?

    If you requested an unlock from the carrier the device is locked to, they advised you they had approved an unlock, then generally the method to complete the unlock is to restore the device as new through iTunes, at which point you will see a message on iTunes when complete that says, Congratulations, you iPhone is now unlocked.

    Where did you get it? In some (not all) countries, it is possible to purchase unlocked phones directly from Apple. Some carriers in some countries sell unlocked phones. Some carriers in some countries offer unlocking of iPhones.

    HOW DO I KNOW IF MY IPHONE 4 IS UNLOKED?

    Did you buy it from Apple or an Apple authorized reseller and did you specifically request an unlocked iPhone?
    Otherwise, there is no way to tell from the phone itself.  Stick a SIM card in it and see if it works would be one test.  Plug it into iTunes and update or restore it, then try a SIM and see if it works would be a better test.

  • How do I know if my iPhone 4 is unlocked?

    So I had lost my original iPhone 3 weeks ago.  And I had to go out to buy a new iPhone without contract for $699. 
    The new unlocked iPhone came out this week for $749.  So i decided to go to the apple store and see what they can do since I wanted the unlocked iPhone.
    They returned the phone I got .. and they just resold it back to me.  They told me to do a restore from backup and it should be unlocked. 
    Now, how do I tell if it is unlocked?  I bought a tMobile micro sim card from ebay so that should be arriving soon.  but is there any other way to determind that my iPhone is unlocked? 

    I think you were given very bad information. If you purchased a new iPhone anytime prior to the last couple of days (when the availability of unlocked iPhones in the US was announced), it was almost certainly locked to AT&T and if so, then no amount of restoration or anything else the Apple Store could do would unlock it.
    I don't think there's any way they could have sold you an unlocked iPhone unless they had them in stock well in advance of the day Apple made the announcement. You can wait until your T-Mobile SIM arrives and see if it works, if you wish, but if it were me I wouldn't wait since that might put me beyond the time when the Apple Store could officially accept a return, potentially making it harder for you to get the issue resolved. I really think you need to go back to the Apple Store and talk to them, preferably with the store manager involved, and get absolutely confirmation, with agreement that you can return the iPhone if the T-Mobile SIM doesn't work, that the iPhone they sold you is indeed unlocked.
    Regards.

  • How do I know if a iPhone 4s is Unlocked?

    I'm buying a unlocked iPhone 4s from craigslist tomorrow. I just need to know how I can verify if it is unlocked. I have an old AT&T sim card I used to use for my iPhone 4. Not sure if that would work.
    I just want to make sure it isn't sprint, or verizon with a bad ESN or something. I just want to make sure I can use the phone.

    If it is a true factory unlocked phone then the model number will be one of the following:
    MD234LL/A 16GB Black
    MD237LL/A 16GB White
    MD241LL/A 32GB Black
    MD244LL/A 32GB White
    MD2257LL/A 64GB Black
    MD260LL/A 64GB White
    If it is a phone that was purchased locked to a carrier and then officially unlocked the only way to tell is to do a factory restore in iTunes and see if it displays the "This iPhone is unlocked" message afterwards.

  • How do I know if my IPhone 4S is unlocked or not?

    I have an IPhone 4S running OS 5.1.3- I think. I am just curious to know how to determine if it is unlocked. I am a current ATT customer.
    Thank you

    Unless you requested & AT&T approved your unlocking request, your phone is locked to AT&T if it came with an AT&T sim card.

  • How do i know if my iphone 4s is unlocked?

    just wondering how long from when vodafone ireland texted me to say my iphone was approved for unlocking and that i should sync it on itunes until when it is actually unlocked and does this show up on itunes?

    If you've received an SMS telling you that your unlock request has been approved, connect your phone, iTunes running & restore it from backup. You should see the "Congratulations" screen once the restore completes.
