HELP how to find out which carrier an iPhone is?

[tensai717171]

I have an iPhone which is locked with a service provider, but I do not know which one it is. Is there any way to find out?

Settings > Carrier. Or check if it has a aim card slot maybe.

I can't even start up the iPhone ... It's telling me to plug it into iTunes and all I am able to do is emergency call ... I was told that it was jailbroke but then I put it into recovery mode and now it's not jailbroke anymore so I need to put in a factory sim card any idea guys??

What generation iPhone is it?

You can probably call apple and ask them to look up the IMEI to tell you.

Go to apples website. Then go to the section under store where you can check to see if you have a warranty. Type it in and then it will tell you what kind of iPhone it is and what carriers it can be used for.

It's an iPhone4 and I typed the serial number in and didn't give me much call the apple support and then they said they have no way in telling which carrier the iPhone is locked with. I guess I will just have to wait for a greater jailbreak software???? So sad

The jailbreak isn't determined by the carrier.

Where is the iPhone 4 from?

[tensai717171]

That's the problem I do not know...bought it off from a friend

[i.Annie]

Is it extremely vital to know what carrier? Are you looking to jb/unlock or are you wanting to use the official carrier

Right now I can't use the phone...i have this screen on the iPhone says plug it to connect to iTunes... And when I do iTunes telling me my sim card is not supported any idea??? Thanks

Looks Like your gonna need to jailbreak it and unlock it.So what happened is that it worked and then you plugged it into iTunes and restored/updated it??
Now it doesn't work?

edit:noticed it was an iPhone 4*

I don't think theres an unlock for the iPhone 4 yet (with 4.2.1 fw and the 3.10.01 Baseband) I assume you now have....

Maybe a custom Firmware?? I don't think you can downgrade the baseband on these yet either? Maybe someone can chime in??

[tensai717171]

Thanks man and yea it was unlocked and I restored it with iTunes latest fw and now after restoring it iTunes is telling me my sim card isn't supported so...I am thinking if I can find out what carrier thus iPhone is purchased from then I can bottom someone sim from that network then plug it in then jailbreak it would that work?? But first I need to find out which carrier it is with thanks again guys!!

[Mr Squints]

it would get the phone "Activated" but when you put your sim card back in you wouldn't be able to use the phone without an unlock.....

Rumor has it that the unlock for 4.2.1 firmware will be released when 4.3 is out..by the end of the month.....

Then all you'd do is turn the phone off, put it into DFU and jailbreak/hacktivate it...then unlock it...
