Hey All, I think I found a possible fix for those who upgraded from 3G, 3GS, or 4 to the 4S and also restored from a backup. I found that after I did a "Reset Network Settings" my 3G speeds doubled (on AT&T). See the attached screenshot of before/after the "Reset Network Settings". Before: After: This worked for three 4S phones I tested on, two were upgraded from 4, and one from a 3GS. They were all three restored from backups. I am not sure if it works for Verizon or Sprint, but I know it works for AT&T. Hope this helps!
