iPhone unlock?

[shanusaran]

Just picked this iphone up from a friend of mine when he went to the army. I have no idea how to unlock this thing to use on sprint or sell to someone else to use. I have software version 3.1.3 build version 7E18, how do i go about unlocking this thing? Im a noob but i do have technical know how, im not technically illiterate So in other words, point me in the right direction!

You can only use it on the official carrier that is gsm. Or unlock it for another gsm carrier. Sprint is a CDMA network.

Ok, how do i go about unlocking it for another carrier? Oh, and what is this phone? is it like an iPhone 3g, 2g, 3gs or what? (Sorry if this is a stupid question...)

How to tell:

iPhone 2G: Looks like this -


iPhone 3G: Looks like this -


iPhone 3GS: It looks exactly like the 3G. You can see the difference if you open up the camera app; if there is an option to switch between pictures and video, it is a 3GS. Also, hold down the home button; if a voice control pop up comes up, it's a 3GS.


As for the unlock, you have to check if you have an unlockable baseband. Go to Settings > General > About > Modem Firmware. What does it say here? If it says 5.14.02, you're out of luck and your iPhone cannot be unlocked.

Otherwise, if you're already jailbroken, navigate to Cydia, then go to Mange > Sources > Add > http://repo666.ultrasn0w.com

Then search for ultrasn0w and install that. That should unlock your iPhone for you.

JREED, you need to update the baseband to 6.15.00 which may break your GPS.

You may also never be able to restore to a stock firmware.

If you would like to proceed, you will need redsn0w 0.9.6rc14 and a stock 4.3.2 ipsw. Run redsn0w and select to update the baseband.

Hi,

Thanks for your information. I don't want to break my GPS. I use GPS often.

Do you have any idea how long takes for that new redsn0w comes out for Baseband is 05.16.02 Unlock fix?

Thanks again for your help,

The software you're looking for is ultrasn0w to unlock, not redsn0w. And it doesn't seem like it's ever gonna come. I think they're working on a way to downgrade the baseband as they're run out of hacks. I haven't seen any twitter updates regarding ultrasn0w at all.

Yeah the unlock for not just the 3G/3GS but also the iPhone 4 have no made any progress for a long time now. It might not be happening any time soon. Nobody knows for sure.
