The HTC One X sold by AT&T Wireless can serve as a portable Wi-Fi hotspot capable of giving up to eight devices Internet access over a 3G or 4G connection. WPA2(AES) security is turned on. I tried the hotspot mode in a variety of locations and got downstream speeds of between 1Mbps and 5Mbps. I couldn't get the HTC One X's near-field communications feature to work--I was unable to transfer a file between the phone and a Nexus 7 tablet. However, I wasn't able to investigate the problem further, so I can't say for certain that it was the phone's problem.
