What’s meaning By Baseband

How to Unlock iPhone 4S, 4, 3GS, 3G baseband ? Before we talk about baseband you have to know the definition of baseband: iPhone baseband is essentially the cellular modem firmware on your iPhone, upgrading baseband is to improve the functionality of the cellular modem and also to keep the device locked to the intended carrier.

This is why iPhone unlocks are updated to different baseband versions while updating their firmwares, since ‘hacking’ the baseband is necessary to allow the jailbreak and unlocked iPhone to utilize the cellular modem on the phone, there by allowing call, data, and SMS transfer to occur on the device.

How to know your baseband

In order to know your baseband version or Modem Firmware go to “Settings”  –> “General” –> “About”–> “Modem Firmware”

Unlock iPhone 5, 4S, 4, 3GS, 3G baseband :

iPhone 5 Basebands

iPhone 4S Basebands

iPhone 4 Basebands

iPhone 3GS Basebands

iPhone 3G Basebands

Note 1: You have to know that updating baseband 5.16.05, 5.16.02, 5.16.01, 5.16.00, 5.15.04 to 6.15.00 (iPad baseband ) will affect their devices by some risks check below the risks and then the choice is up to you:

  1. If you update your device to baseband 6.15.00, you will not be able to restore using the original firmware. That means you will face an iTunes error message if you try to restore it directly from there. You can only do it via a custom or ‘cooked’ firmware created with redsn0w or other tools.
  2. There is no software downgrade available once your baseband has been upgraded to 6.15.00. However.
  3. GPS will not work properly or in may not work seriously on your iPhone due to this baseband although a fix is said to be on the horizon.
  4. You will void any Apple warranties as they can easily detect this baseband if you bring it in for service.
  5. The resale value of your iPhone may be lesser due to the above, that’s if you intend to sell it at one point. Otherwise, this is not really an issue.
  6. At the end you will stuck -on the 6.15.00 baseband forever.

Note 2: iPhone 4 users who will use GEVEY SIM have to know that GEVEY solution will help them to unlock their iPhone 4 running 4.1, 4.2, 4.2.1, 4.3, 4.3.1, 4.3.2, 4.3.3, 4.3.4, 4.3.5, 5.0, 5.0.1, 5.1 and 5.1.1 firmware on baseband 4.10.01, 3.10.01, 2.10.04, 1.59.00 and this GEVEY SIM is available here for only $22.99.

Note 3: iPhone 4S users should pear in mind that GEVEY Ultra S will unlock GSM iPhone 4S running iOS 5.0, 5.0.1, 5.1 and 5.1.1 and also will unlock jailbroken CDMA iPhone 4S running iOS 5.0, 5.0.1 and 5.1.1, GEVEY Ultra S is available for purchase for $39.99 GSM and $49.99 CDMA and you can get it for here.

Note 4: locked iPhone 4 users should take care from baseband 4.12.01, 4.11.08 cause these basebands are unlockable with out solution so if you are running a lockable baseband so you have to preserve your baseband if you decided to update your firmware from here.

Note 5: Now you will be able to downgrade from the iPad baseband 6.15.00 to 5.13.04 that will fix the famous GPS issue and help you to unlock your device  devices using ultrasn0w.

  13. David says:

    If you are using AT&T, you can follow their instructions on their website to factory unlock your iPhone 4. Go to AT&T’s website and search for “Unlock iPhone”. Go to the first “search result” (not the products from AT&T) and follow the instructions. It may take a long time (it took 8 days for AT&T to unlock my iPhone), but it worked for me on my iPhone 4 iOS 5.1.1 baseband 4.12.01.

    Ok don’t listen to people that say they can do something when there high on tweek. I bought a iPhone 4s in early sep of last year. My friend said he could jail break it for me. Me not knowing anything about it said ok. 1st problem iPhone 4s 5.0.1 9b406 something close I can’t remember. Did not have a jail break out for the 4s. First time it was teathered. Got home reset it and it was stuck going off and on at the lock screen. Went back he did it again. I did really lookin into what I should and should not download. It was was to heavy for me at the time. So upgraded to 5.1.1. Said fuck it. Now it’s in like a weird state. I can trigger the spring board. By clearing all the apps on my dock. Then move one app to bottom right and springboard resets. Anothr. Is playing trigger AirPlay with Siri. ????? Apple didn’t know shit.

  34. Jack says:

    Hi Dev team, how much apple paying you not to distribute unlock for bb 4.11.08/4.12.01?? I know you have already done this, but I can very much guess apple hold you not to distribute this to public to maintain iPhone 4S sales am I right?

    I guess Joker was right ” If you’re good at something, never do it for free” ha ha ..

  35. Jack says:

    My wild guess, this unlock will be made available after the release of iPhone 5 … so we might want to wait until then, then.

  36. Doug kennedy says:

    Is unlocking and jail breaking the same thing

  37. maxx says:

    so the solution exist but will be released after Iphone 5 will be public? then bring it on I5 so we can unlock our locked iphones

  45. osas says:

    please you have to help us oo. am also into the same problem.. iphone 4, version 5.1.1, BB 04.12.01..please we need your help

  46. aissajez says:

    Look buying a new iphone 4 now will be automatically on version 5+ so it it’s 4.11.08 or 4.12.01 baseband which of course you cant unlock, so il you are buying sealed it better be factory unlocked (no carrier buy it from apple store at higher price count for some 600$) if its factory unlocked no matter whih baseband it runs, you can use it worldwide with any carrier, otherwise look for some 1.59.00 baseband (used iphone) so you can use it with ultrasn0w (best option).

  47. aissajez says:

    you can unlocked if your carrier (that this iphone is locked to) does support this factoryunlock option. (if you meant Telus canada, yes it’s supported) you have to be out of contract (finish the 2 years of contract or whatever) you pay them some 100$ (less or more im not sure it depends on the carrier) and you’re factory unlocked forever.

  50. Rafael says:

    Hi David, have you tried jaibreaking the phone after it was unlocked?Do you think it’s going to stay unlocked whatever future iOS we use and whatever baseband there is?Since there’s already a way to jailbreak iOS6 if the phone is factory unlocked theoretically you could have an iPhone 4 iOS 6 jailbroken and unlocked. Am I right or do I miss anything?I’ve got one more question – do you think my phone is going to work if I take it now abroad, I sent att an unlock request a minute ago. What I mean is – is it necessary for the device to be physically present in the country of origin after the 5-7 days they require to perform the unlock? Or is it going to work anywhere, how do they actully make it unlocked, anu idea? I got an iPhone 5 today so the SIM in the old one does not work anymore. BTW thanks for sharing
