If you have bootmii installed as boot2 you don't need preloader as a recovery method, but the hacks are nice.
I did not see any mention of ios60patched being installed prior to your preloader, so I will assume you did not install it?
If That is the case
Install your system menu wad
Preloader can prevent disk updates and be used to boot directly into a homebrew app, bootmii can probably boot into an app as well. I would install preloader.
If preloader is uninstalled, just instal ios60patched, then preloader.
