Boot Chain
VROM->LLB->iBoot->Kernel->System Software
One of the iPhoneLinux goals are to replace that Boot Chain after iBoot:
VROM->OpeniBoot->Linux Kernel->X Server->Window Manager
Upgrade Process
Restore Mode
The common upgrade process chain is VROM->DFU->WTF->iBoot->Kernel->Ramdisk->Restore Mode.
DFU Mode
To flash an older version of the iPhone software you have to let your phone reside in DFU. In iTunes you have to press the option key (Mac) or the shift key (Windows) when pressing 'Restore' to be able to manually chose an IPSW.
