i'm watching this tread, and wondering if op installed preloader.
I have the exact same problem, install patch ios60 as wad and OP if you get upside down HBC when you install the truchabug, i fixed it by running DOP IOS MOD.(don't now if i that's the correct way to fix it)
OP if you install preloader by installing ios60 with DOP IOS please tell me, i have the same conf. as you.(exept i could install 4.1 then i installed ios 60patched from wad manager)
