I am purchasing an iPod Touch, and want to Jailbreak it. I have looked at all kinds of tools, ZiPhone being my favorite, if it did not downgrade the boot loader. I am leaning towards iLiberty for mac, but I do not know how to install the Installer.app then. If anyone can share their experiences and toughts about... A) What all the terms like Boot Loader, Flashing, etc... mean? B) What the best tool is that DOES Not downgrade the bootloader for good (can be reversed) that is easy and safe C) Install the Installer.App Thanks for any input. I am truly a newcomer to this, and am very confused. Please Help!
