I had the same problem (just installed .97) and couldn't get the browser icon to show. The "email settings" icon was missing as well as some others.
I've installed different OS's before but never had this happen. The only thing I could determine that was different this time was that I had installed custom themes since the last OS upgrade. These themes have customizable icons on the main menu and for some reason it wouldn't allow the browser icon to appear, along with the others even after resending service books and following the usual procedures after an OS upgrade. I reset to a factory theme and viola, there were my missing icons. Flipped back to the custom theme and everything was still there.
