Downgrade to iOS 4

Bravadin

I have been looking around here and google but am very confused. My question is can my factory unlocked 3GS be downgraded from iOS 5.1.1 to any lower iOS. The phone is running very slow and I would sacrifice any of the benefits of the later os for the speed of the phone when I bought it. The phone has not been previously jailbroken. From my searching it seems I'm out of luck but I live in hope of the clever people here knowing of a solution.

Thanks for the reply guil. I'll go away and cry now over my slow phone. Ah well have to wait for iPhone 5 and then my son can complain about how slow this one is lol

Sometimes a clean restore can do the world of good on a 3gs if its slow after an update

If your device is jailbroken you can disable lots of the features which you dont need which should improve performance

Oops, I have just read that your phone was not previously jb so ignore the below.

YES YOU CAN. But...
You need to have had the phone jb when you were on the ios version you want to downgrade to.

If that is the case, the blobls are saved on cydia, so you can jb now and downgrade using tiny umbrella.

I hope you did jb, otherwise you would be using 30% of the capacity of the phone

Same problem with the ipad 1. Wish I'd never updated to ios 5. It's just so slow now that I hardly ever use it anymore.

I know you've corrected yourself already but thats. It always true either. Say someone had a 3GS on 4.3.3 and decided to jailbreak after ios 5 was released. They couldn't save the shsh blobs for 4.3.3 if apple weren't signing the firmware anymore

My ipad 1 is running ios 5.1 and its perfect but hear lots of complaints admittedly.

There are a few ways to speed up a 3gs a small bit.
Turn off icloud
Disable spotlight
Google
