If you're looking for information outside of the U.S., InfoLink is not available. There's not a way to enable the feature in other regions, since the information for other regions doesn't exist. (Weather, stocks, etc). What region are you inquiring from?
I bought an UN40B600 and expected it to have the info link option available. I did not understand why it was not avaiable until I saw a small varation in the model number, and found out my TV was made for a region that had this feature disabled. I am really frustrated about this because the commercials from Samsung did not make this clear. Any how, I was wondering if there is a way to enable this feature. Thanks for your time.
