Why is the obligatory answer to everyone's questions on this forum to root?
I know there are numerous advantages to rooting, but there is always a next step that involves installing a new rom.
Some people do not want to root or rom their devices and possibly enjoy the stock interfaces.
That being said, as mentioned before, at&t will put out a OTA that will add the features. They were later releasing the device, yes, but at&t usually tests their updates for a few months before releasing them on the network for all to have.
