The most simplest way to root your Android device is by downloading a App from the market, just type in One Click Lag Fix in the search box and it will show up. Once you install this app, just go to your app menu and click on it. In it, it will give you series of options to choose, first, click 'root device/phone' after it does that, reboot your phone and hold the power button and the volume buttons at the same time when you turn it back on. When you see the menu where you are in download mode, use the volume button to select download packets. Once that is done, then your phone is rooted. After your phone is booted up and ready to go, go back to OCLF and click on 2.0+ lag fix, this will put your phone on plane mode and will take a while to finish. Once it does finish, it will reboot and turn back on (By itself, I believe) once you get to the Galaxy S logo (Before your phone is booted up and on it's UI) it will take a while, so DO NOT PANIC! It takes about 2 to 3 minutes for it to load up. After that, you're set and you may do what you wish to do! NOW ENJOY! :'D Note: You must have a high end phone for this and it must be running Eclair for you to install this.
