I have a samsung captivate model SGH-I897. But I have ATT so they call it the Galaxy S. So Kies mini finally got the 2.3.5 Gingerbread update, and I went ahead and used it to update from 2.2 Froyo. Immediately afterwards, my wifi ceases to function entirely. I'm sure many others have had the same problem. So I guess I need to roll back to 2.2. How can I do that in android? Isn't there a way to do that without having to go through all the hassle of using Odin and going and finding 2.2 somewhere?
