Well, as fas as i remember, for an Hackintosh (OSX 10.5.X) we need an EFI Bootloader which can be installed on any Intel Machine (AMD also, but Intel is more close onto the orig.) iOS is based upon OSX, so that being sad, we could try to port this bootloader onto our n900.
If i remember correctly, there was also OpeniBoot for the iPhone 2g and 3G so they also could boot Android.

I fully understand that we are Linux users and love our advantages, but i think this would be some really good peace of cake we could bake^__^

If i have completed my exams by Monday, i will start learning coding...
I´ll see what it gives after some time.
