Does an iPhone 3G have to have a valid SIM card in it to complete an authorized unlock from AT

Have a 3G now superceded by a 4S.  AT&T is the network.  Want to unlock the 3G so it can be used in Mongolia.
Requested an unlock from AT&T and it was authorized but when I connect the 3G to iTunes and do a backup and restore I don't get the unlock confirmation.  THe SIM card in it is the old AT&T SIM card which is now invalidated because the 4S has the new miniature SIM card.
AT&T support doesn't know if the SIM card in the iPhone when I complete the unlock has to be valid or even if there must be a SIM card in the phone or not.

No carrier "automatically" unlocks at end of contract - many won't do it at all, even if requested.  I don't know what your carrier's policy is since you didn't say what country you're in.
However, if I understand you correctly, you didn't change carriers so it doesn't matter if it was unlocked or not. Try the following steps, as needed:
1. Reset phone - press both home and sleep/wake buttons for at least 19 seconds until the Apple logo appears
2. Settings > General > Reset > Reset Network Settings
3. Restore phone in iTunes using a backup
4. Replace SIM card (don't care what Telstra says)
5. Restore phone in iTunes as new, without using a backup
6. Take phone to Apple.

    I can not get to iPhone screen, so no way to get to Settings. That is the problem. When I connect phone to iTunes I get screen asking to insert SIN card. On the phone I'm getting Cinfigure screen asking Launguage , Country or Region, Wi-Fi, ( I can connect to my home wi-fi), and last screen "Activating your iPhone". After two minutes of waiting IM getting message: Your iPhone could not be activated because the activation server in temporary unavailable. try connecting to iTunes or try later or contat apple.com/support.
    Like I mention, I went to Bell as well Rogers store and tried to insert active SIM card with no results.
    Yes, my friend unlock the phone to use with Rogers but I don't know where

  • HT5704 Since updating to iOS 6.1.3 on my iPhone there have been odd sim card messages, and now my wifi button in settings is not accessible. Also huge battery and data drain. Any suggestions?

  • I've broken my iPhone and have put my sim card in my old iPhone 3. If I plug my old iPhone 3 into my computer, will it update the iPhone 3 with everything that is on my phone that is now broken, or will it 'update' iTunes with what was on the old iPhone?

    Plug your phone into the wall charger for at least 30 minutes...make sure you have a sim card in the phone...then:
    Leave the USB cable connected to your computer, but NOT your phone, iTunes running, press & hold the home button while connecting the USB cable to your dock connector, continue holding the home button until you see “Connect to iTunes” on the screen. You may now release the home button. iTunes should now display that it has detected your phone in recovery mode, if not quit and reopen iTunes. If you still don’t see the recovery message repeat these steps again. iTunes will give you the option to restore from a backup or set up as new.
    Make sure you have no anti-virus software running or any firewalls...turn all of that stuff off.

  • Does the iPHONE 4s have a changeable SIM?  I cannot get the SIM door to open to check.

    Does the 4s have a removable SIM card?  I have not been able to open what is shown as the SIM compartment to make this determination.

    You need to push quite hard.
    But regardless, if you have a GSM iPhone with the SIM card tray, then you can change the SIM card. Whether a different SIM works on your phone depends on whether the phone is unlocked.

  • Old iphone for wifi gaming now needs valid sim card on ios7?

    Hi. I have an iphone 5 with a contract. Been using my old iphone 4 for a year on wifi without a contract for games. Updated 4 to ios7. Now it won't work without a valid sim. What to do?

    Thanks Michael. Guess I'm stuck for now then. Can't use my iphone 5 sim (which is on the same carrier), as that's a nano sim and I don't have an adaptor, so have purchased one today. Unfortunately am out of town, so nobody I can borrow a sim from for now. Shame, as I've been happiy using my old phone for over a year to game on wifi without a problem. Wish I'd known this before attempting to upgrade the ios!
    Stll, thanks very much for the quick reply - I'll follow the advice once the adaptor arrives.

    The CDMA iPhone 4 does not use a SIM at all. There is no SIM slot. It is a pure CDMA phone.

  • Does the iPhone 4S have a shutter on the camera?

    A month or so back my iPhone camera had something half blocking the lens. I was just wondering, is this the camera shutter? Or does the iPhone even have a shutter?

    It has a virtual shutter... but there is nothing physical other than a case or possibly your finger to block the lens.

  • Does the iphone 4s have voice assisted gps navigation system when ion is downloaded to the phone?

      does the iphone 4s have a voice assisted gps system when io6 is downloaded onto the phone?

    The iPhone has NEVER had an International Warranty. The warranty terms state, quite clearly, that Apple "may" restrict warranty & support to the country of original purchase. The only exception, are iPhones purchased in the EU, where the iPhone warranty is EU wide.
    You purchase an iPhone in Singapore, & you will have to return it to Singapore for all warranty & support issues.
    For iPhones out of warranty, Apple has an out of warranty replacement program.

  • Does the iphone 5 have gorilla glass?

    does the iphone 5 have gorilla glass?

    Apple has not said what the screen is made of nor the vendor of the material. Most likely it is a an aluminosilicate glass from some vendor, but whether it's from Corning or some other glassmaker is unknown.

  • Does the iPhone 5 have Flash

    Does the iPhone 5 Have Flash?

    The Puffin browser, available in the app store for a few bucks runs flash via a workaround.  You can get a free trial version which will run flash for 14 days so you can see if it does what you need.  A side benefit of Puffin, is that it displays full web sites, not the mobile web sites.  This is very useful for some purposes such as banking options not available on mobile.  I got it for a trip I was taking, and still use it from time to time when a site doesn't display properly on Safari.
