Thank you for all comments, ideas and links!
First, if you live within the US or have access to the AT&T network, you should try to see if you can get an OTA update. If your phone is, unrooted, running a stock ROM and you have a valid AT&T SIM card, you should be able to get an OTA update. Otherwise, you can go to the thread below for instructions on doing a 2-step upgrade to the latest version (4.3) ...
First, use Odin to flash 4.1.1. If you need the 4.1.1 stock firmware (I747UCDLK3), you will find it at the bottom of the above thread. Flash this via Odin. Thereafter, download the two zip files for 4.1.2 and 4.3 respectively to your computer and save to a good quality micro SD card. Place the card in your phone. Boot your phone to recovery mode and flash the 4.1.2 zip. Allow installation (flashing) to complete, then power down and reboot to recovery again. Repeat the process for the 4.3 zip. That should do it. Good luck!
