The Dev Team has released a procedure by which you can dual boot your iPhone into different firmware versions.
The dev team has been using dual-booting to jailbreak the iPhone for several
months now, however now that several more advanced techniques have been
developed (many of which are still private), I thought it apropos to release
this cool hack for those who would like to dual boot multiple versions of
the iPhone software (or other OS's) from their handset. It's a neat little
hack that I think might be useful for developers playing with 1.2.
Essentially the procedure involves creating a new partition on the iPhone and installing a different firmware version on it.
We will release a tutorial shortly for those interested in doing this. For now you can read more
here.
The procedure is brought to you by NerveGas, planetbeing, ghost_000, dinopio, bgm, MuscleNerd and the combined iPhone-Elite and iPhone/iTouch Dev teams.
