no you need a computer to do so
no
There is no way to control your iPod Touch from your computer without jailbreaking. Even if you were jailbroken though, I don't believe there are any modern packages that could help you.
yes you can just go to cydia and download mewseek if jailbroken
you get cydia by going to cydia download ipod touch thanks ]
Cydia costs $9.99 on iPod touch.
Cydia is an app itself you get when you jailbreak your iPod touch. You get it when jaibreak is finished, if you have greenp0ison, you have to go on loader and download Cydia from there. If you use redsn0w, you will have the choice of downloading Cydia from your computer to your iPod.
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
Restore with backup
You dont download it on you ipod. You download it on your computer
No, you must jailbreak and get cydia to be able to download an emulator.
There is no way to install Cydia without jailbreaking.
You can get Cydia on the app store but you have to jail break your iPod so it can work with the app.
