You can get an installer without Jailbreaking it, using a program called 'Pusher'.
I don't now a other way to get cydia of but the only way I know how to take cydia of is to restore your iPod touch
well..
First you need a jailbroken iPod touch. Then go to cydia and type up mx tube.
Cydia is like the appstor for hacks, basically anyhing is now possible on your iPod.
After you jailbreak the iPod touch, you can pretty much do anything you want. If you have jailbroken the iPod Touch that means you have Cydia and you can add sources. Look up "What are some good sources for Cydia?" to find some sources.
simply you have to have a jailbroken ipod touch iphone or ipad and have cydia downloaded whacth vids on utube
No. Only if you download a jailbroken device and have cydia to do it.
Installer has been discontinued. Use Cydia or Icy
yes you can just go to cydia and download mewseek if jailbroken
After you've jailbroken your iPod, open Cydia and go to the bottom for Manage, Click Manage Sources and then Add the source.
U can get dtunes from cydia if ur iPod is jailbroken or get a idownloader from iTunes and download it from that.......also f### the haters:p
Well,yes anything that is from the AppStore. And a few things on Cydia.
