Dual-booting the iPhone
Posted 12 March 2008 @ 7am in Guides/How-Tos
Dual-booting is an oft-used solution in the desktop realm, where users value the capability to boot multiple versions of an operating system from the same volume (e.g. Windows Vista and XP, Mac OS X Tiger and Leopard, Mac OS X and Windows on Intel-based Macs). Now a similar solution has been released for the iPhone, allowing users to boot multiple iPhone OS versions (e.g. 1.1.1 and 1.1.4) from the same device. This capability may come in handy when a future, SDK-compliant iPhone OS release (2.0) is released and users with to maintain compatibility with old “jailbreak” applications while taking advantage of enhancements in the new release.
Detailed by Jonathan “NerveGas” Zdziarski, the process is quite involved and requires some command line work. Zdziarksi writes:
“I’ll 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.”

This would be more interesting if someone ported Palm OS and Linux to the iPhone…
I’m sure it will happen at some point…

@ libertyforall1776 …
Why would someone port Palm OS to the iPhone? For what god awful reason would you want to use that antiquated piece of junk on an iPhone?
And why bother with Linux when you have OS X on the phone? Any Linux app you may want to run on it you could modify it to work with the native OS?
I see a reason to have two versions of the iPhone firmware. I don’t see the purpose for doing what you purport…
