AT&T’s 3G network has had its ups and downs, well most of them were downs, so that’s why the company is going to be introducing N-SET. N-SET stands for Network Settings Solution and it will be rolled out this month. This new trick will supposedly balance traffic between the carrier’s 2G and 3G networks and reduce the load on the 3G network. What that means is that AT&T customers will use 2G for voice and 3G for data usage. Will that be enough for AT&T to enhance its 3G network performance before the new iPhone arrives?
