    NOTE: If you're viewing this via a mobile application... tap your screen to view in a compatible browsing window. It'll allow you to see the Baseband lists below.

    Here we're going to outline all the Unlockable Basebands for the iPhone 3G, iPhone 3GS, iPhone 4 (GSM Only), iPhone 4S (GSM Only) & iPhone 5 (GSM Only.) and the methods of doing so. The most common misconception associated with iPhone Unlocking is that it relies on what iOS version you're running... this is false. Unlocking relies strictly on what Modem Firmware or "Baseband" your iDevice is on. In order to determine what Baseband your iDevice is follow this path, Settings>General>About... then look at the designating #'s next to "Modem Firmware." In addition, this outline does not include any iDevice that runs on a CDMA network (Verizon or Sprint). Those iDevices CANNOT BE UNLOCKED in any way outlined below.

    In terms of Unlocking there are three methods...

    1. The software version called "ultrasn0w" This is a package downloadable via Cydia, after a Jailbreak, through a stock repository that comes with Cydia. This method allows you to use any compatible GSM Sim. For the majority of users, this is the desired method since it doesn't require anything more than Jailbreaking. Then downloading the Ultrasn0w Package from Cydia. For iPhone 3GS or iPhone 4 users on iOS 6.0, iOS 6.0.1, or iOS 6.1, you must install UltraSn0w Fixer for iOS 6 in order for your unlock to work.

    2. The hardware version called a Sim Card Interposer The only Sim Imposters that we recommend to use are Gevey Sims. The Gevey Ultra (iPhone 4) & Gevey Ultra S (iPhone 4S). This is due to it being the only legal option, in most areas, because it does not require you to dial an emergency number to complete the Unlock process. The Gevey Ultra (iPhone 4) supports iOS versions 4.0, 4.1, 4.2.1, 4.3, 4.3.1, 4.3.2 & 4.3.3. The Gevey Ultra supports the 1.59.00, 2.10.04, 3.10.01 & 4.10.01 Basebands. It will also support iOS 5.0, 5.0.1, 5.1 & 5.1.1 ONLY by preserving the 04.10.01 Baseband. The Gevey Ultra S (iPhone 4S) supports all iOS versions, 5.0, 5.0.1, 5.1 & 5.1.1. As well as all basebands; 1.0.11, 1.013, 1.0.14, 2.0.10 & 2.0.12. There are MANY Sim Card Imposters sold under the “Gevey” or “Ultra” name that simply do not work. Thus, we recommend that Gevey products only be purchased from a trusted supplier like Applenberry.com.

    3. Installing the 6.15.00 iPad Baseband (3G & 3GS Only) Installing the iPad BB should only be utilized as a last resort. WARNING!!! The iPad BB IS NOT compatible w/ iPhone 3GS' manufactured during or after week 34 of 2011 (see below to determine when your 3GS was manufactured). Doing so will render the cellular radio inoperable. Installing the iPad BB will essentially LOCK it to this BB and, in most cases, cause your iDevice to lose GPS capabilities. Any future iOS updates will require updating w/ a custom IPSW. UPDATE!!! The newest version of redsn0w v. 0.9.14b2 will allow users w/ a 3G or compatible 3GS' (mentioned above) to downgrade from the iPad BB back to the 05.13.04 BB. Thus regaining full use of your GPS fuctionality and allow you to upgrade your iOS using stock IPSWs as opposed to creating a custom IPSW. If in the event you choose to take this route... the 6.15.00 iPad BB can be acquired via an option during the Jailbreak process using redsn0w.

    *** To determine the manufacture date of your iPhone 3GS you check the 3rd, 4th and 5th digits of your serial number. The 3rd digit is the year(i.e. if it was an "8" your phone was manufactured in 2008, a “1” was manufactured in 2011). The 4th and 5th digits are the week of that year in which it was manufactured (if the 4th digit is a "3" and the 5th digit is a "4" then your iPhone was manufactured in the 34th week).***


    **Update**


    For new bootrom 3GS users. You can try another method to have your baseband downgraded to a feasible baseband. This mandates that you have iOS 4.1 blobs for your device. If you do not have them for your device, this method will not work.
    1. Downgrade your iPhone 3GS (new bootrom) to iOS 4.1
    2. Flash your 3GS with the iPad Baseband.
    3. Downgrade your iPad Baseband to 05.13.04
    4. Upgrade your iOS while preserving your baseband
    5. Jailbreak your device and unlock using UltraSn0w. Use an UltraSn0w Fixer if applicable
    Below we will list each iDevice, it's Unlockable & non-Unlockable Basebands, and what method is required for that particular Baseband.

    No, 04.11.08 is not unlockable. We will update the post when and if a solution becomes available.

    Correct. While it's possible to downgrade your iOS version... there's no way to downgrade your Baseband.

    I found an article that says it might be possible to share activation tickets between users on the 04.08.11 baseband. Is this something i should be excited about, the article is about a week old. Also some guy claims to be able to factory unlock iphones locked to the at&t network (only at&t though). He says its legit and approved by apple or something. No way to tell how legit it is though.

    No, you cannot share unlock tickets. Factory Unlocked means that the device was unlocked at the factory, so anyone who claims they can perform a factory unlock is lying. The only way for AT&T iPhones to become officially unlocked is to call AT&T and ask them to unlock the phone if the device is off contract.

    Oh I am going to hazard a really rough guess on this one. Bet he has a buddy that works for AT&T and they skip the current "verification process" that AT&T recently put in place. I bet that buddy charges for that override privilege.

    But that is just a guess on my part.

    I have been searching and trying to follow tutorials on how to unlock my phone but nothing has worked thus far. I am hoping that someone responds.

    I have an iPhone 4 with 4.3.3 and firewire 04.10.01

    I used redsnow to jailbreak the phone and I know have cydia. I then tried to use Ultrasnow to unlock (repo666.ultrasn0w.com) and it ran the script. I have my AT&T sim card (thats the carrier I want to use) but I get no service or invalid SIM.

    I am doing this wrong or using the wrong scripts? Or do I have to use Gevey Ultra (which I would have to purchase)?

    Thanks.
