iPod Touch 2G iOS 4.2.1 Jailbreak

Hello.I just want you to comment this text. Well , I wanted and I still care about asking you something , I care about asking you a specific and simple--well , not really simple thing about a jailbreak of any iOS device-well my iOS device is an iPod Touch , pretty much difficult to jailbreak.(for people who do not have an idea for what does ''jailbreak'' means , witch is not so possible , read the description : jailbreak of a device is an illegal unlock that you do with your device by various ways. Well, with the jailbreak you hack your device. You can do something like... everything with your device.)Well , I want to jailbreak my iPod Touch 2G (second generation) iOS 4.2.1 firmware. I don't care with what program I jailbreak it , unless the program is bad. I do not want programs that are not safe. I want safe programs to do the jailbreak , and I do not want them to require stupid things , like : domains , personal password , and you know , this kind of shit. I don't like these things that they cause you into troubleshooting and others. I like simple programs. Programs like greenpoison , blackra1n , limera1n , and a sort of redsn0w. They just tell you to press sleep button , them home button and then release the sleep button and keep holding the home button and after 5 minutes the jailbreak is successful ! But , once I have jailbreak my iPod Touch , I updated it and without knowing , while I was updating it the jailbreak was dying!!!So , the other morning I got up , I opened my iPod Touch to feed my fish , you know , I have a game with fish , called Tap Fish , anyway , as I opened it , there was NO JAILBROKEN DEVICE!!!!No homescreen wallpaper.No iPod Touch 3G abilities. No Cydia!!! No Winterboard. No iFile. Generally , NO JAILBREAK!!!Well , comment this text by helping me. Write in the comment box step by step HOW TO JAILBREAK IPOD TOUCH 2G IOS 4.2.1!!! REMEMBER!!!!

PS: By the way,
Merry Christmas!
