Many carriers have officially released OS 6.0 for most devices the latest one to officially bless the 9700 with OS 6.0 is T-Mobile USA. The software has to be updated when you plug your 9700 to your pc via USB cable and launching desktop manager. If the OS is available for you it will prompt you to upgrade to v126.96.36.1998. That is one of the versions that was leaked a while ago but if you been waiting for the official version plug your device to desktop manger. I was able to grab the screenshot when I plugged mine into the pc. Thanks to Tashana for the tip. This is an official OS but the warning still applies always do a backup before any upgrades.
There is no official word from T-mobile but it looks like it will be official soon.
Update looks like I forgot that I had loaded .461. One of our readers pointed out that the update is actually .448 not .461
