crasher8521 March 2, 2011, 4:25 am

You have to put it on there. it doesn’t come with it. First go to Cydia. then go to sources. Then edit and add. and punch in- “http://cydia.hackulo.us”. Then go to search and search for installous. Then install it

Jake January 14, 2013, 6:07 pm

My ipod touch is not jailbreaking. Why? I tried using iOS 4.2.1, but it doesn’t work.

PCubs01 May 12, 2011, 2:24 am

Yah same thing with me. It shows the emblem, but then the apple insignia takes over and it reboots normally.

memeluvswiz May 26, 2011, 10:38 pm

i jail-broke but then when i went to the loader and clicked cydia it said that cydia has already been installed.. so i clicked on the cydia app and all it does is nothing.. it wont open up at all .. what should i do ?? please help

Lee June 5, 2011, 2:57 pm

So, does this support touch 2g (mc) on the latest firmware (this question has been asked many times on this page, with no answer)? I can’t get it to work so I’m guessing no.

Any other ideas?

Kevin June 24, 2011, 11:56 am

How do u do dis peice of shit

SFSDF August 12, 2011, 5:16 pm

snowbreeze was the only jailbreaker that worked for me. after several attempts with greenpoison and redsnow, finally discovered snowbreeze. I used 2.2.1 on my ipod touch 2g mc model
try it out!

SheriS October 8, 2011, 7:00 pm

Betatestxp October 19, 2011, 8:08 pm

Stop bitching and google your questions.
Greenpois0n works perfect with the last 4 iTouch 2g MC I just did.
