I really hope that jailbreakers will be able to downgrade iPhone 4S from iOS 9.3 to iOS 6. I stayed current when Apple released updates, even with terrible performance, but now it's really doesn't make any sense to stay on that laggy iOS 9, if I could use blazing fast iOS 6.

It's now only 4s. iPhone 6 is getting more and more sluggish with every major and even minor update.

Source for that? My iPhone 6 is as fast as ever. It's just not the fastest phone around anymore.

Personal perception. I am using iPhone6 for two years already. It is in no way objective.

Just curious: Is it possible to stay on an old release forever with an iPhone, or do they force the upgrade eventually?

[vbezhenar]

They don't force upgrade. With iOS 6, new update is downloaded automatically and it's not possible to remove this update, so you're wasting quite a lot of precious disk space (but if you jailbreak, you can remove this update).

Also I'm not sure that it's possible to do factory reset and stay on old version. But as long as you don't do that and don't press "upgrade", you'll be fine.

How do you get apps for the old iOS versions? They are no longer in App Store..

[vbezhenar]

AppStore allows to download latest app version supported by your operating system.
