used blackra1ns program. took 2 seconds and worked flawlessly. this shit is way awesome. i mainly did it to enable tethering, which i did, and im using it right now since i dont have internet at my house. im really surprised by how fast the speed is! currently running the "lush" theme found in cydia. super sexy. is it easy to revert back? what do i do when an OS update comes along? i dont want to lose all the mods and shit ive done. what will happen?
