to fellow jailbreakers out there, Apple is cracking down on jailbreaks, they have blacklisted previous OS for the iphone and itouch. I called them, and what I learned was very important. The New Itunes 9.1 release is capable of detecting jailbreaks, and if apple executes it, it is also capable of bricking your itouch/iphone permanently, untill you update it to 3.1.3. Apple has digitally unsigned the old 3.1.2 or lower OS'es, so itunes will not use them. the only one you can use to update or restore now is 3.1.3. This is a sad day for software programmers. To all, DO NOT download itunes 9.1, and DO NOT update to 3.1.3. It is rediculous how apple is trying so hard to kill all jailbreaks, instead of putting new features into the ipod. BE CAREFUL!!! you can still sync your music with no worries if you have itunes 9.0 or lower. just do not update.
