    Hello,

    My wife got a new iPhone 3GS last week and I was thinking if I can downgrade the iOS to a past version. I think iOS 5 runs kind of slow in the 3GS... the previous versions were smoother...

    Actually, I found iOS 5 runs pretty well on a 3GS. If you set it up as a new phone, it'll be pretty quick.

    You can downgrade 5.0 to 4.3.3/5

    Did you back up your SHSH blobs?

    Key Phrase: "He got her a new 3GS...". Meaning no previous SHSH blobs.

    Not sure if they still are, but in recent history Apple was still signing 4.1 for the 3GS. You could try to downgrade to that. If the iPhone does in fact have other SHSH blobs saved from more recent versions, then all you need to do is run TinyUmbrella's TSS server when you DFU restore as new and make sure you shift-click to point to the proper .IPSW.

    I've hear stories of people buying "new" iPhones that had previous blobs saved to Cydia. Apple probably repackages returns.

    Oh I know it's not completely unheard of, but it is highly unlikely.

    Do you mean to restore the phone... even if it's a new phone

    Well, my wife's iphone 3GS is still slow... sometimes it takes several seconds to open an app and messages.

    I'm doing a full restore to the phone to see if that helps.
