I thought I would start this thread as our '1 stop shop' to find information on about the new JB. what i know: 10:10 am GMT 10/10/10 when it will be public SHAtter and greenpoison are /only/ possible on the fourth-gen devices: iPad, iPhone 4, and iPod touch 4G SHAtter itself is tethered. comex came up with a way to untether it on 4.1/3.2.2 Maybe some of the smart dudes here can provide info: is it for life?, if so, why? will there be a way to 'de(un)-jailbreak' ie. restore to factory state. for example if JB isnt for you or you want to sell it and remove the JB. what are the risks?
