AT&T will start throttling data for the Unlimited Data subscribers starting the first week of October. AT&T will be adopting a similar plan to that of Verizon and slowing down the speeds of the network’s top data hogs. The reason is because AT&T is trying to curb the problem of data congestion and overall network issues that have hurt the 3G network’s performance since the iPhone was introduced. The throttling plan will work like the others’. The heaviest users will see significant speed decreases for one billing cycle once they go over a threshold of data (we’re guessing 2-4GB?). These heavy users will still be able to access the network, but at a much slower speed. At the start of the next billing cycle, their speeds will return to normal. AT&T will also be releasing its first LTE devices later this year.
