A fair number of users have found that after upgrading they iPhone 3G[S] to iOS 4 they were discontent with the results. In many cases iOS 4 has caused iPhone 3G’s to become extremely slow and even more unresponsive than prior to the ostensible upgrade. If you are unhappy with iOS 4, follow these simple instructions for downgrading from iOS 4 to iOS 3.1.3:
The process should work nearly the same on Windows and OS X, so unless we say otherwise, you can follow the same steps on each. The main difference between Windows and OS X is RecBoot, so Windows users, make sure you pay close attention to the RecBoot process before diving in. The same basic steps should likely work for iPhone 3GS, according to our 3GS-toting intern Adam Dachis, who’s used a similar method in the past. (Still, I haven’t been able to verify, so proceed at your own risk, and if you do, let us know how it worked in the comments.) Lastly, you should read through the entire guide before you dive in, just so you know what you’re getting into.
Was all of this part of Apple’s master plan to “force” people to upgrade to the iPhone 4? Somehow I doubt it, as that is just a little too far-fetched and conspiracy theory-ish.
While I have noticed a considerable slowdown in iOS 4 on my iPhone 3G I do not plan to downgrade. The upgrade is quite compelling even if somewhat slower than iOS 3.1.3, as I simply adore the unified inbox and folders, among the few other features iPhone 3G owners were offered.
What about you – are you noticing such a severe degradation in speed after the upgrade that you are considering downgrading?
