i want to hopefully start working on creating jailbroken devices in the form of mobile substrate dylibs and other tweaks, I don't have much experience at all but I'm sure I'll be able to pick it up easily, I have OS X Lion installed along with Xcode 4.2 and iOS 5 sdk, which is the firmware I want to work with

my question is, how would i set up a template for dylibs and setup the simulator to run test them, also, is there anyway to set up the simulator to have all native apps along with sbsettings or uisettings
