Update: Sorry for providing a tutorial for Unetbootin, but it might be helpful if you're having problem with the dependencies.
Command Line - using dd
You can make a live USB using command line.
- Download the ISO.
- Insert the USB stick.
- Run
sudo fdisk -l and note down the device name of the flash drive. You would be able to find it somewhere near the bottom lines. For example, let the name is /dev/sdb1.
Use the following command to write the ISO on the flash drive:
sudo dd if=/path-to-the-iso/Fedora-16-x86_64-Live-Desktop.iso of=/dev/sdb bs=8M
You'll need to enter your password to run this and previous commands as root with sudo. To have the ability to run programs as root, you'll need to be a member of the group wheel.
Important Points:
- The name of the device should be used i.e.
of=/dev/sdb and NOT /dev/sdb1. It is because sdb1 is the name of the partition, not the device.
path-to-the-iso should be replaced with the path where the ISO is. For example, if it is located in /home/user/Downloads, it should be like if=/home/user/Downloads/Fedora-16-x86_64-Live-Desktop.iso.
- The name of the ISO file should be changed according to the version downloaded.
dd would format the flash drive, so make sure to take a backup, if you've any files you don't want to lose.
Command Line - using live-iso-to-disk tool

Using Unetbootin
Edit: Although the screenshots are from Ubuntu, they won't differ much in Fedora (except for the look, ofcourse). They are given just for reference.
Install unetbootin.
sudo yum install unetbootin
OR you can get it from their website.
Install syslinux and p7zip
sudo yum install syslinux syslinux-extlinux
sudo yum install p7zip p7zip-plugins
Execute unetbootin
You should access it this way if you've downloaded it manually, from the website.
sudo /<path-to-the-executable>/unetbootin
If you've installed it from the repository.
sudo unetbootin
If you've already downloaded the ISO, select the iso and the flash drive and click OK.

You can also select the distribution and the version, if you don't have the ISO. Although the list may not be updated, so it is recommended that you download it directly from the distro website.
