hey guys soo there is no current jailbreak out yet for 4.0.1 or higher as most people know

there is a jailbreak for 4.0 as most of u know is called thetechgame.org which the u go to on your idivice via safari all u do is "slide to jailbreak".

also if u want to downgrade your idevice from 4.0.1 or higher u can find all the firmware files here [ Register or Signin to view external links. ] and then when u are in itunes u can restore to that firmware by clicking shift as you click restore and then u can jailbreak again with thetechgame.org

PLASE NOTE: u must have your SHSH blobs saved in cydia to downgrade

u can also jailbreak iphone 2G,iphone 3G and ipod touch 2G which has the latest firmware with redsn0w which can be found here [ Register or Signin to view external links. ]

thanks and i hoped this helped
