If you were going to hack your iPod Touch, be careful. Apple is gonna come after you, boy.
After taking a pretty hands-off stand against iPhone hacking, they are getting very hands-on against iPod Touch hacking.
A hacker named "Martyn" was going to upload the NAND data from an iPod Touch to the web, which would have made hacking a lot easier for others, but Apple put a stop to it through his ISP.
Perhaps they are trying to hide things in the iPod Touch that they haven't announced quite yet?
