how cani tell if its been unlocked from three network, previous owner upgraded and sold methis and i paid for 3 to unlock but its been 10 days n omly takes 3sim

Did you follow the steps to unlock it and get the message, "Congratulations, your iPhone is now unlocked"?

There is no unlock code for an iPhone. You must follow the instructions you received, and if you do it correctly and the phone is unlocked you should receive the message deggie mentioned.

If you do not follow the instructions it will not be unlocked.

If the phone was ever jailbroken it will not be unlocked even if 3 processed the unlock request.

Your instructions should have told you to put leave the SIM in it, connect it to your computer and Restore your iPhone as a new phone in iTunes. Did you do this?

Yes, after you receive the message I mentioned above.

You don't get an unlock code !

The system is the registered user contacts their Mobile operator confirms iMEI number and pays appropriate fee.

That Mobile operator submits the iMEi number to Apple.

Apple white list iMEi number on their iTunes server and confirms this back to Mobile operator.

The Mobile operator sends the registered user an sms/e-mail inviting them to sync phone via USB cable to their ITunes account.

You follow on screen prompts (With registered sim onboard) until you see the “Congrat's .........” message

You now pull the registered sim and replace it with a sim from another supported network.

Caveat with some of the Virtual networks such a Giff-gaff /Virgin / BT/ Tesco etc........ you may have difficulty getting SMS/MMS to send due to the APN settings being wrong (They default to the actual network sighted).

Some of those Sims may give you access to a hidden menu feature that allows you to set the correct APN manually however others don't.

hi i stillav not got anywhere, i dont know if there is something im doing wrong or what but previousowner upgraded 3 network contract to iphone 5,i doubt shed av had a contract phone jailbroken cos she wunt need to,she trannsferred all her stuff from i phone 4 n gave me the phone, she then filled in the network unlock form with three and i think paid for it by card or maybe it is added to first bill of upgraded cos three say that on website, she then recieved an email to say unlock has now been processed and to change sim and connect to itunes, i already had the phone atthis point she kept her sim, so i didnt av a 3 sim to keep in phone wqhilst syb with i tunes and as that was not on instructions from 3s email i tried with t mobile sim n vodafone and o2 and got no service, i then got a 3 sim n tried the phone it worked with 3 sim so i tried connecting with itunes n got no unlock, iv spent 2 weeks trying all this n cannot unlock, me n previous owner both been on phone to 3 and 3 was doing the restore as new phone whilst connected to me on phone and with access to my pc but itd get righty to end n disconnect n cancel saying internal error,

I find it almost impossible to understand what you are saying, with no punctuation or sentence structure. So there's not much I can do to help.

If you get an error restoring (I think that is what you said) I need to know the exact error message and error code number.

my space bar isnt working well however its not all that hard to read, question, can this phone still be unlocked without previous owners sim card

Yes. Previous owner's SIM card is not required. I found it very hard to read, and I'm still not sure what you said. Your "." apparently isn't working either, and neither is your shift key.

NO !

I have already told you of the process and how things need to be done above.

The lock is achieved by associating a specific Sim card IMEI number and Network identifier.

To unlock All these must correspond with the information submitted to Apple by the Mobile service provider

In this case “3”.

The original owner Sim must be onboard !

one says yes other says no,?????.come on guys get the xmas spirit and cheer up, ha ha ... the previous owner has tranferred ownership to me with 3 network it doesnt appear to work how iv tried and i i need help on start to finish with a 3 sim and then any other network sim i want to use, this is a valid purchase from a friend who,d upgraded, everything has been done legal 3 will av given apple the previous owners details when they request unlock to which they have passed on to previous owner who has inboxed me instructions on how to do it but its not working ....i couldve jailbroken it now had i wanted to bend the rules however i want it doing correctly and would be very grateful if you guys would help me do so ...p,s and q,s if n when required.... thank you

You said that you got an error updating. That problem must be resolved first, or it will never be unlocked. What is the error number?
