I had my old 3G sim card in my 9900. So yesterday, after reading this thread, I called att and was told that in order to use 4G network I need a 4G sim card. I had a 4G sim card at home, so I was able to upgrade.

So far, since the upgrade, I noticed only 1 change - I no longer have an option of choosing 4G/3G or 2G connection mode in Mobile Network menu.

I have not noticed any increase in data speed.
