Your "3.41" pkg runs on 3.15 and drumroll unjailbroken!
Amazing job xttl, your "3.41" pkg is the first homebrew to run on my 3.15 unit unjailbroken. I did of course have to run jailbreak to install it. So you can remove the 3.41 designation. This is amazing news, and I don't care if it works for homebrew only, this is great. No more wear and tear on power switches, and USB ports, no more dongles for boots except for installing.
Can you write up a quick mini-tutorial on how you did it? Like what is different in the 3.55 pkg? That won't install for me, I get an error. Obviously you are using under PSL1GHT, but details please? Thanks.
