As incredible as it may sound, there are still plenty of people searching how to unlock iPhone 4 and other old models like iPhone 4s, iPhone 5, iPhone 5C and iPhone 5s.
Maybe some of you still remember the good old ultrasn0w, the very last free iPhone Unlock software. But is it possible to still use it on an old iPhone model?
Can you still unlock an iPhone 4 to iPhone 5s for free with ultrasn0w download?
Right now you can buy online an unlocked and well-preserved used iPhone 4 with $28 while a used iPhone 5s with difficulty reaches $70.
It is only logical for someone not to want to spend a single dime to unlock an old iPhone and still less so for an iPhone 4.
Until the beginning of 2014, it was perfectly possible to unlock an iPhone 4 to iPhone 5s completely free by using ultrasn0w 1.2.8. But is it still possible in 2019? Let’s find out.
Ultrasnow 1.2.8 Free Software Download
The only free iPhone unlocking software that has ever existed is no other than Ultrasn0w.
Available in various versions with the last update being 1.2.8, it was a sure but not permanent solution.
Usable up to iOS 6.1.6, all you had to do was to jailbreak your iPhone, install Cydia and finally download ultrasnow for free via repo666.ultrasn0w.com.
With a good success rate (around 90%), you could unlock your iPhone but:
- You could not upgrade to newer iOS from there on without losing the unlocked state
- In case of restore, you would have to repeat the whole process from scratch
iOS Soft Dev Pack download
In fact, Jailbreaking and Cydia even gave you the option of removing the iCloud Lock free through iOS Soft Dev Pack for iPhone 4 to iPhone 5C.
Free iPhone Unlock in 2019
As I said, ultrasn0w 1.2.8 free unlock software as well as iOS Soft Dev Pack can be used up to iOS 6.1.6 but here is the thing: It’s been many years since the last time you could downgrade to iOS 6.1.6.
Apple made it impossible to downgrade iOS unless you have upgraded to a beta version of a future update for testing.
So even if you are able to find any of these tools there is no way to use them.
In 2019, the only way to unlock any iPhone for free is via the mobile network services that has locked it. Of course, the iPhone must be absolutely clean to accept the unlock request.
So, if you bought a used iPhone, regardless of model, and you want to unlock it for free, you should know:
- In which carrier is locked
- Its full IMEI state
Luckily you can learn everything about an iPhone instantly with a Full IMEI Check Service.
Of course, if it is proven that the iPhone is not compatible with a free carrier unlock service, you will be offered the best and most economical alternatives.
The cost of third-party iPhone Unlock services depends on the model and it’s naturally cheaper for older iPhone models.
Whether it’s worth paying to unlock an iPhone 4 is exclusively at your discretion.
