Roll back firmware . . .

Sep 10, 2010 10:16PM PDT

iPhone 3G. The latest update 4.x has made my iPhone very sluggish. I found a link to previous versions of firmware, specifically 3.1.3 with simple instructions, and promptly lost it. Can someone supply a link?

Thanks large.

I have that one. The one I lost was one file, .bin extension, iTunes would rename it to some other extension. Then iTunes would update/roll back the iPhone.

The one in the .zip file has several files and folders and I don't know how to use it.
