I've warned that this day might come, and, according to Engadget, it looks like January 8 is that day. Not only is AT&T bumping up the price for those of us with AT&T grandfathered unlimited data contracts, it is going to stop offering subsidized phones for signing up with a two-year agreement. If you are eligible, you might want to upgrade by January 8. You will have to do so online or in an official AT&T Retail Store as the carrier stopped letting Best Buy, Apple, and other retailers offer subsidized AT&T phone plans many months ago.
