It had to come to fruition eventually: AT&T will being throttling the “top 5% of smartphone data users” who use a lot of data. As AT&T stated, “One new measure is a step that may reduce the data throughput speed experienced by a very small minority of smartphone customers who are on unlimited plans – those whose extraordinary level of data usage puts them in the top 5 percent of our heaviest data users in a billing period. In fact, these customers on average use 12 times more data than the average of all other smartphone data customers.” They also are very careful to mention that they will not be throttling everyone, just a small percentage of users. Either way, it still sucks.
