I'm buying an iPod Touch 3G tomorrow and am wondering if it would be possible to downgrade the OS from 3.1.1 to 3.0 so I could then jailbreak it? Would this slow down the iPod since the 3G is not meant to run 3.0? Would other problems come from doing this? I really want to jailbreak my iPod Touch when I get it and there is no jailbreak available for 3.1.1. so I really want to downgrade... An alternative would be to wait for a JB for 3.1.1, does anyone have any speculation on when this could be released? Thanks.
