When using the Wi-fi hotspot, it looks like the only options for the Security on the Wi-fi side are open and PSK-2. I can not make PSK-2 work with any of my computers using WindowsXP. I know XP is getting pretty old but it is still in pretty wide use. I really would like to use my Acer netbook while without having to run the hotspot in the ope mode. My Droid X would let you run the Hotspot in WPA1 which worked great.
