I am using a jailbreak but without Cydia/Icy/Installer. I only use the jailbreak to modify some files like wallpapers, sms ringtones etc.
From what i have heared is that Redsn0w and Pwnage will copy the Applications map to another partition? Is this correct?

I don't want that, because then the Applications map will be twice on my iPhone (?).

Is there a way to jailbreak my device but without moving the applications map?
