AT&T,
All of sudden your network is not congested anymore because now you can profit from the new customers and double their data. But to the ones that have paid for many years an unlimited service, you are throttling their data to crawling speeds. Sometimes I am not even at the 2.5 GB mark and you have slowed me down. In your website states that smartphone owners may get throttle at 5GB. But you don't even wait for that, not even 3GB...VERY UNFAIR, VERY DIRTY TACTICS. Not a happy AT&T customer.
