1) I have downloaded 1.1.3 ipsw...then i decrypted ramdisk and filesystem... now i have access to both decrypted ram disk and File system. Using decrypted ramdisk i was able to get the secpack.. But my question is What could be the next possible step for hacking?? To be specific how can i jailbreak and activate manually without using any tool like ziphone or something like that...??? where should i patch? can anybody provide some details please?

2) what is the use of Lockdownd file? and whats the use if it's patched?
