Apple Stops Signing iOS 10.3.1

by

IPSWFollowing the release of iOS 10.3.2 on May 15, Apple has stopped signing iOS 10.3.1, the previous version of iOS that was available to consumers.

Customers who have upgraded to iOS 10.3.2 will no longer be able to downgrade their devices to iOS 10.3.1.

Apple routinely stops signing older versions of software updates after new releases come out in order to encourage customers to keep their operating systems up to date.

iOS 10.3.2 is now the only version of iOS 10 that can be installed on iOS devices by the general public, but developers and public beta testers can download iOS 10.3.3, a future update that is being beta tested and could see a release in the near future.

I know that Apple gets criticism for not supporting older versions of its software, but having the majority of the iDevices on the same version is great when you're a developer.

It is also great for the merchant when everyone buys nothing but the same things.
I don't want to call the developer lazy if they don't want to code for different versions of devices, but I am running out of vocabularies.
It is simply a proven fact that older devices runs slow with newer OS, so the consumer has every right to keep their device running an OS that is optimized for that.
I dunno if u r a dev.... otherwise calling developers lazy only shows how entitled people are nowadays....

The manpower to support a number of ver of fragmentation for a moderate sized app, which often goes for 99 cents or something, can easily be hundreds of thousands of engineering dollars. Not all developers is their own Facebook....

If you don't want the latest features, security patches and app compatibility, you probably ain't the ones that will compensate developers fairly for their work either. As a developer, I can totally do without these audiences and not develop for them. Not running a charity here

What about the iPhone 5C? Wasn't 10.3.1 the last iOS?
32-bit devices are supported until iOS 11.
I really can stand consumers who refuse to upgrade. Older versions have known exploits. You put your own data and those around you at risk when you intentionally run outdated versions. Sure each update may have some issues, but these days security needs to trump stability.
I have skipped iOS X on both my devices - iPad Air 2 on 8.4.1, iPhone 6s+ on 9.3.3. So, it's nice to know you can't stand me. ;)

Think I will finally be updating the iPad Air 2 to iOS 11 this fall, the new multitasking features are too good to pass up.

Fragmentation doesn't mean more work. It means a dev has to make his app work with the lowest common denominator if they want to support the widest amount of users. It means the dev won't be able to use the newer APIs, it doesn't mean more work.

iOS 10.3.1 was a great release. I installed it on my iPad Air and runs flawlessly. I don't plan on updating any more, because iOS 11 surely will lag on 1GB RAM devices. And I don't like the new Control Centre xD(...)
I too consider 10.3.1 one of the best releases of iOS 10. I tried 10.3.2 two times with DFU(and had considerable drains out of the box both times) and all the betas of 10.3.3(which did not solved the drain issues), only 10.3.1 showed no battery issues whatsoever. It returned my 5S to its former glory.

(...)On the other hand, I've read iOS 10.3.2 has battery issues, so I'm waiting to 10.3.3 to upgrade my iPhone SE, wich currently is on 10.2. Probably, I won't update it anymore too, I see iOS 11 too cluttered on this 4" screen. And man, my SE is Sooo fast now....
You should update to +10.3 since your SE's NAND will benefit from APFS. It improves several aspects of data management which augments performance, while improving longevity since reduces write operations.
