If I remember correctly, before I temp rooted the phone, when I went to settings->wireless & networks->tethering & portable hotspot, the "Portable wi-fi hotspot" option is greyed out. After temp rooting it using Visionary r14, I could enable hotspot. And after I reboot the phone(unroot), I expected the option would be greyed out again but it didn't. I was able to enable wifi hotspot without rooting it again. I was just wondering if anyone is having the same thing. Thanks
