_Guide to Unlock iPhone 4 Running iOS 5.0.1 with InstantiPhoneUnlocker.info
_If you are locked on a
particular carrier on your iPhone 4 device, then UltraSnOw 1.2.5 offers a
reprieve for you to sample what other network carriers have to offer. This is
particularly the case for people who had updated their device firmware to
version iOS 5.0.1 and found that they were stuck in the middle of nowhere. This
post gives the complete details of unlocking iPhone 4 devices that are running
on iOS 5.0.1, including which basebands qualify and how to proceed with your.
Qualifying Basebands
The only limitation to your unlock iPhone 4 5.0.1 is the baseband level. If probably you updated your previous baseband to a higher version while updating your device’s firmware, then your device might not qualify for this unlock. You will first of all have to downgrade your baseband before proceeding.
Baseband downgrading isn’t also an abracadabra, and you have to know exactly what you are doing. The main challenge with baseband downgrade is that you have to downgrade your firmware, and that is only possible if the particular lower version is being signed in by Apple. If not, then you are locked in the middle of nowhere until iPhone Dev Team or any other iPhone unlock team comes up with another safer alternative.
In short, the following basebands qualify for unlocking iPhone 4 with UltraSnOw 1.2.5: 01. 59.00, 04.26.08, 05.11.07, 05.12.01, 05.13.04 and finally 06.15.00. Anything outside these options or a baseband downgrade that can’t land you on any of them means that your unlock can’t be possible with UltraSnOw 1.2.5.
Jailbreaking iphone 4 on iOS 5.
Before you can unlock your device, you first of all need to jailbreak it. RedSnOw supports a semi-tethered jailbreak on iPhone 4 5.0.1 new bootrom and untethered jailbreak on the old bootrom. You can read more about semi-tethered, untethered and tethered jailbreaks on a separate article on this website. However, assuming that you are having the new bootrom, then proceed with your jailbreak as follows:
Step 1: Download iOS 5.0.1 as well as iTunes 10.5 from the relevant websites.
Step 2: Make a backup of your iPhone 4 and once done, use the iOS 5.0.1 IPSW firmware file that you just downloaded.
Step 3: Download the respective RedSnOw 0.9.9b8 if you are using Mac OX or Windows.
Step 4: Launch the RedSnOw that you just downloaded and then go to Extras > Select IPSW . Locate the iOS 5.0 IPSW file here.
Step 5: Click the Jailbreak option to start the iPhone 4 jailbreak. Your device should automatically guide you into DFU mode, and then click on the Install Cydia option.
Step 6: When the jailbreak is complete, your iPhone should automatically reboot. If it doesn’t, then do it manually.
Step 7: Launch RedsnOw again and then go to Extras > just boot. If you have an old bootrom, this last step becomes an optional move since your jailbreak will be untethered.

Once you are done with the jailbreak, follow the steps below in unlocking iPhone 4.
Step 1: Tap on cydia and then go to Manage > Sources.
Step 2: Go to Edit > Add and once the editor opens, type the UltraSnOw address http://repo666.ultrasnOw.com to search for it in Cydia.
Step 3: once you find UltraSnOw, install it on your iPhone.
Step 4: Perform a tethered boot and your unlocking iPhone 4 bid should finally be successfully completed.
This unlock iPhone 4 guide should successfully unlock your device. Ideally, an untethered jailbreak is better than a semi-tethered one since it doesn’t tie you to a computer boot all the time. However, that depends on your device bootrom and whether it is new or old.
Secondly, some people usually experience problems and therefore do not end up completing the unlocking iPhone 4 process successfully. Instead of panicking about this, check for some minor technical errors that you might have committed in the steps above. For instance, downloading the wrong RedSnOw version or downloading the correct version but for a wrong platform could bring about such errors. In such a scenario, just restore your device and start the unlock process afresh.
If you are not sure about anything as far as unlocking iPhone 4 is concerned, it is better to ask than proceeding in the wrong way and damaging your device in the process. And always remember than jailbreaking and unlocking iPhone 4 voids your device’s warranty, so do it safely. And lastly, it makes no sense to pay for an unlock, unless you feel philanthropically charitable to do so.
