I was successfully able to root and create a wifi hotspot with the Samsung Galaxy Prevail that I bought 2 hours ago at Best Buy. Yes, I know its been said that it is close to impossible, but they were wrong. Heck ya! ok, I looked around for a root that actually worked until I found one, unfortunately I extracted it to my desktop and named it something else, so the author is unknown, but the great news is that IT WORKED! ok, so first extracted it to a folder on the desktop, then put your Prevail in debugging mode and plug it in to the computer. Make sure that you have the Prevail's Drivers installed on the pc too. After that, remove the SD card from the phone. Open the folder on the desktop and open the file named (root). Follow the directions that pop up on the screen from there. Then, when you are done, go to android market and download a file called BusyBox. BusyBox will only install once you have successfully rooted your phone. REBOOT the phone. Then go to android market again and download an app called Wireless Tether. Install it and you are ready to go. Then connect your devices! HOOORRAAHH, and guess what, it was freakin easy!
