Each Apple device has its baseband which is mostly changed after new iOS update. You can find out what iOS 8 baseband you will get after you install this most recent version of mobile operating system on your smartphone.
The new iOS 8 was officially presented to public for download on September 17. This is when the testing of this operating system has begun through devs installing it on their devices and searching for bugs which are reported to Apple. The company is fixing problems in the next beta update. The latest beta version released is beta 4, but there should be a couple of them before the firmware goes public in September.
You can learn what baseband on the iPhone with iOS 8 upgrade you get. This firmware drops support for the iPhone 4 devices. If you have the iPhone 5, 5c, 5S or 4S you can be sure that your device supports iOS 8 on your gadget and this is how your modem firmware will change.
Baseband for iOS 8 iPhone Models
The build version 12A4331d gives the following versions of modem: iPhone 4S users get baseband 5.4.01, iPhone 5S and 5c owners get baseband 3.07.01 and iPhone 5 users get baseband 7.02.03.
iPhone 4S – 5.4.00
iPhone 5 – 7.03.00
iPhone 5C – 3.09.01
iPhone 5S – 3.09.01
iPhone 6 – 1.00.05
iPhone 6 Plus – 1.00.05
Whenever you are updating your firmware version with Apple, your baseband changes unless hackers create a program that allows preserving your old baseband during upgrade. This could play role for jailbreaking. Once you change your baseband version you cannot downgrade it to previous one, so think twice when you decide to install iOS 8.
iPhone 5S has been improved and got exclusive features that are not available to other smartphone models. Those who spent money on the locked gadget are now looking for a way to unlock iPhone 5S iOS 7 device. Is it possible? What should you do if you have already updated to version 7.0.1?
Users who purchased their model from U.S. carriers can easily unlock their smartphone via IMEI tool. This factory method is fast and reliable. It is not free though but it’s way cheaper than buying the never-locked iPhone from Apple.
iPhone 4 users who have installed iOS 7 would probably like to downgrade or unlock baseband 4.12.09. How is it possible to do? Is there an easy solution to both problems?
We hope you haven’t upgraded to the new iOS 7 without having your baseband preserved if you had a device unlocked with Gevey SIM or Ultrasn0w method. This way you will lose your unlock and won’t be able to perform the same procedure for your new firmware because both Ultrasn0w and Gevey SIM jailbreaking unlock methods don’t support the new iOS 7 yet [no one knows when and whether they will be updated].
If you are searching for the way to downgrade iPhone 4 04.12.09 you might find some instructions but don’t follow them. You will never succeed. It is sadly impossible 4.12.09 downgrading to previous modem versions. Why? We’ll explain this to you.
Smartphones created by Apple can’t be downgraded after you have upgraded their iOS version / baseband. Sadly, such protection is used so that hackers or other people couldn’t damage the gadget via discovered exploits.
In other word, having the smartphone with such baseband you are stuck with this modem firmware. You can only update it in the future when iOS 7.0.2 is available for public download. There is no method for iOS 7 jailbreak yet, but you are able to unlock your handset even with the latest baseband.
There is no software / hardware unlock for iPhone 4 users. The only way to unlock this model is via factory unlock solution which relies on your IMEI number. If you know your IMEI code and original operator your gadget is locked to you can find a reliable company that offers iPhone unlock by IMEI number and order this service. You’ll have to pay for such unlock but it will be guaranteed and successful if you have the smartphone that was activated with the carrier and is not blacklisted [sometimes it is even possible to unlock a barred IMEI number].
Step 1. Contact the company and make sure you are eligible for unlock [the smartphone is activated, you know the carrier name and IMEI code].
Step 2. If you got an iOS 7 device from a reseller ask its previous owner to turn Find My iPhone app off. Otherwise you won’t be able to activate the device and use it.
Step 3. Order factory unlock service for your iPhone 4 with baseband 04.12.09 and wait till the status of your device is changed to forever “unlocked.”
Use your unlocked gadget and follow the new. Maybe it will become possible to downgrade 04.12.09 baseband in the future [if hackers find such a way].

After looking at these baseband you realize that there is no free unlocking solutions for such versions. Only SAM can work with iPhone 4 and iPhone 4S if you have activation tickets saved half and a year ago.
Otherwise not Ultrasn0w, not Gevey, R-Sim, X-Sim , TP-Sim or other solution will work. And is bad news. But not bad as it may seem at the first glance. There is one way that supports any iOS / baseband firmware.

Finally iOS 7 was released. Many iPhone 4 users has updated their firmware and got 04.12.09 modem firmware. And big part of such users now need to unlock 4.12.09 baseband.
Those who used unlocking solutions like Gevey or Ultrasn0w, which were dependable on iPhone modem firmware version, lost unlock after iOS 7 update. Unfortunately hackers haven’t released tools yet allowing to preserve baseband while upgrade. I hope they will soon.

Update: If you stuck on one of these baseband and need to hack it, you can try it using BBTool, DLOADTool, DBLTool and iOSUSBEnum developed by p0sixninja.
As you see iPhone modem firmware has really changed in all iOS 7 supported devices. if you really wish to try the new firmware but you afraid to lose software/hardware unlock you can read about benefits of official unlock and free your iPhone from the carrier’s chains to enjoy the first iOS 7 beta firmware with updated baseband.
While one hackers working on iOS jalbreaking the others on baseband hacking. Now it is possible to hack iPhone baseband of the newer models. There are four tools that were written by P0sixninja to hack only with Qualcomm hardware iPhone 5, 4S and 4 (CDMA). There is a possibility to access iPhone 5 baseband using Minicom and Signal 2 app but here is something different.
You can use BBTool, DLOADTool, DBLTool and iOSUSBEnum to boot up Qualcomm baseband’s files which are related to QHSDLOAD protocol (Qualcomm DLOAD protocol). These program will allow you to open iPhone bb giving the possibility to find exploits and try to use them to unlock iPhone 5 and other models. It can be used for raw communication with the baseband like fuzzing. Fuzzing is one of the easiest and most eﬃcient ways to ﬁnd vulnerabilities.
iOSUSBEnum (Utility to enumerate USB (HSIC) devices on iOS)
BBTool (Tool for communicating with AppleBaseband Kext on iOS)
DBLTool (Tool for communicating with Sahara protocol (DBL) on iPhone4 CDMA, iPhone4s, and iPhone5 (Apple SAH Protocol)
DLOADTool (Tool for communicating with QHSDLOAD protocol on iPhone4 CDMA, iPhone4s, and iPhone5 (Qualcomm DLOAD protocol)
Step 5. You can also use DBLOADTool to enter the normal operating mode after DBL mode. As you may guess you will need to step to bbticket, osbl, and amss into DBLTool entering the following command to hack iPhone baseband:
dbltool -b /usr/local/standalone/firmware/Baseband/Trek/bbticket.der -o /usr/local/standalone/firmware/Baseband/Trek/osbl.mbn -a /usr/local/standalone/firmware/Baseband/Trek/amss.mbn
Step 6. Wait up to 30 seconds because AMSS loading may take some time. To see if the iPhone baseband was booted up, you can use iosusbenum command without CommCenter been loaded. The command output should be like these below:
Step 7. To reset the iPhone baseband to its original settings use command:
Seeing this bunch of information you can be sure that you have just hacked iPhone baseband and fully boot it up even without CommCenter. The last thing left is to send commands to iPhone baseband using DIAGTool and QMITool and explore the modem firmware and filesystem in general. Use comment section below to share your experience with booting up iPhone bb.
Unbelievable method to unlock with Ultrasn0w iPhone 3GS on iOS 6.1.3 baseband 05.16.08 (which is not supported by Ultrasn0w). To be honest I found the video on YouTube where the user ultimateidevicevids, showed interesting way to unlock 6.1.3 baseband with famous tool.
Some users have discovered one interesting fact. When they try to google if they are able to downgrade iPhone 04.12.05 baseband they find no solutions to their problem. Let’s take a look at this issue and find out whether we can or cannot perform this task.
The problem is of current interest for iPhone 4 owners who have upgraded to iOS 6.1.3 and wish to downgrade their baseband version afterwards. You can upgrade iPhone to iOS 6.1.3 without baseband update as there is no need to waste your time because right now it is simply impossible to get down to previous basebands once you have updated to firmware v.6.1.3 and changed the modem firm you had.
How to Downgrade 4.12.05 iPhone 4
Having the iPhone 4 you most likely wish to jailbreak it because untethered jailbreak Evasi0n can help users with iOS versions up to 6.1.2. Still you have probably updated your modem firmware to 4.12.05, and different step-by-step guides posted online cannot help you resolve the issue and finally downgrade your smartphone’s baseband.
Apple is trying hard to protect its gadgets and quickly patch exploits discovered by famous hackers. This company is keeping an eye on each utility released to public. It is fast to take steps to prevent iPhone users from unlocking, jailbreaking and downgrading their handset’s modem versions.
The first iPhone 4 modem firmware that came with iOS 4 release back in 2010 was version 1.59.00. It was hacked using Ultrasn0w. This was the only method available till Gevey SIM was presented capable of unlocking basebands 3.10.01, 2.10.04 and 4.10.01. Later SAM Preferences appeared but the Cupertino-based giant quickly patched its servers to stop users from jailbreaking using this method.
As for today, there is no solution on how to downgrade iPhone 4 modem baseband 4.12.05 to previous modem firmware. So save your time and stop following different instructions that promise you a successful solution to your problem. You can unlock your device using official factory unlock tool. Only by using legit service you can forget about the baseband hacking and looking for unlock.
Today you can find out how to unlock iOS 6.1.4 running on iPhone 5 and enjoy your Sim card. If you really need audio profile for speakerphone you can download iOS 6.1.4 and enjoy it with any Sim.
There were times when it was impossible to unlock the iPhone 5 model with 3.04.25 baseband. And it’s not strange because there aren’t any software for this latest phone from Apple. Unfortunately iPhone unlock software method was possible only on older versions with old baseband. For example you could use such software as Ultrasn0w or SAM, etc.
But Apple company removed this possibility by updating modem firmware versions and such baseband as 3.04.25 on iOS 6.1.4 is not unlockable with any software or hardware method.
However, it’s not so bad as it might seem. At the moment, there is a way to perform iOS 6.1.4 unlocking by IMEI number.
The essence of the method is the official iPhone 5 unlock from the cellular operator. Only the operator and Apple company has the privilege, since only they have access to the database. This service is not free as it is known, the operator charges a fee for the change of locked status to “Unlocked” in iTunes database, and the price differs.
How to Unlock iOS 6.1.4 And Where To Find It
Step 1. You can find a variety of sites and services as well as ads in social networks and forums. But there are many pitfalls and scam!
Why not order the unlock through social networks and forums? The answer is simple: there is no guarantee for refund! Only online payment will give you 100% confidence in the fact that you do not lose your money if iPhone 5 or any other model will be still locked.
Be careful in choosing the service, as there are a lot of scammers who took the money for the unlock and will not do anything!
Step 2. Fortunately, you found this post where you can find legit services below. The next step is to find out the carrier to which your iPhone is locked to. If you know it – good, but if not use IMEI network checker and find it out in 2-5 minutes.
Note: To locate IMEI (which is the most important thing for factory unlock) go to Settings -> General -> About and find it or you can just type *#06# and you will see it on iPhone screen.
Step 3. Knowing the carrier go here to find the country and name of the locked network and make an order.
Step 4. If your network is AT&T you the luckiest iPhone 5 owner because you can unlock iPhone 5 iOS 6.1.4 for the cheapest price and fastest delivery time using this AT&T service with official confirmation from Apple.
Note 2: you can use that services not only for iPhone 5 3.04.15 and iOS 6.1.4, but for any iPhone model and iOS version.
Step 5. After IMEI unlocking enjoy any iOS firmware and basbeand and don’t forget that any SIM card around the world is supported by your iDevice permanently!
That is what I call fast, cheap and simple. Just forget about messing up with all those tutorials, errors and complete disappointment. Just use IMEI unlock and enjoy not only iOS 6.1.4 but iOS 7, 7.1, etc.
