Talk about cool.
We’ve all heard of dual-booting desktop and laptop computers with mutiple OS’s. There’s nothing cool about dual-booting on desktop computers – heck, I used to triple boot my MacBook Pro with Mac OS X, Windows XP, and Windows Vista. But, what about dual-booting your iPhone?
iPhone developer/hacker extraordinaire, Jonathan “NerveGas” Zdziarski, has posted detailed instructions for installing and booting from multiple OS’s (firmwares) on the iPhone. The method allows for the installation of, say, both the iPhone v1.1.4 firmware and iPhone v1.1.1 firmware simultaneously. Cool indeed.
The instructions, according to NerveGas, will
“walk you through a sample jailbreak scenario with 1.1.4, using 1.1.1, to show you what I mean. To do this, you will carve out a new partition on the iPhone and install version 1.1.1 on it. You’ll then upgrade the iPhone to v1.1.4, which will leave the new partition intact. You can then dual-boot the iPhone, allowing you to mount 1.1.4’s partition using the 1.1.1 partition.”
Dual-booting the iPhone could prove to be useful as a way to run both official iPhone applications made with the official iPhone SDK and unofficial iPhone applications used with the iPhone jailbreak solution. The iPhone v2.0 firmware that’s expected to work with these official iPhone SDK-based application could be dual-booted with earlier iPhone firmwares that are compatible with older jailbreak applications.
While everyone else is dual-booting their desktops, I’ll be dual-booting my iPhone…
