I upgraded my iPhone 3GS to the new 4.0 software, but I now I want to go back to the 3.xx that I had before. Is there any way to do that?

Why, are you having problems? iOS4 has been very solid on my wifes 3Gs.

Not if you weren't jailbroken and have the SHSH blobs saved.

My 3G is almost useless under iOS4. Texting is slow, I have to touch buttons several times to get them to work, etc. Given there aren't many comments about this, I am thinking it might be my phone or something else. Anybody got any ideas?

With a 3GS unless you were jailbroken before and tapped "make my life easer" in Cydia you can never downgrade a 3GS

Unless you really want to, I would recommend NOT upgrading to iOS4 if you have the 3G. I've seen the 3GS and it's much better.

Actually, if you're lucky enough to still be under the Apple Care warranty, go to the Genius Bar and ***** up a storm. They will end up replacing it with a refurb that has 3.1.3 on it.

I have used these instructions to downgrade in the past, they work very well.
