OK, to get the terms straight. Jailbreak means that you can access the whole files system on the iPod Touch or iPhone. This comes from the fact that what actually happens is that you are “chroot jail” in Unix terms. That means that the root, or the top of the file system also called, “/” is set in a subdirectory so the user applications on these devices can’t see the system at all. Jailbreaking means breaking this so you can see all the files.
The net is that a jailbroken phone can have third party applications loaded and complete customization. If you have firmware 1.1.1 this is amazingly easy because Safari, the browser, has a bug (called the TIFF exploit, this means that if you send the right kind of TIFF file to Safari, it ends up in root or super user mode and you can jailbreak) so if you just browse “jailbreakme.com”:http://jailbreakme.com then you can install applications. It’s that simple, browse and you are there for version 1.1.1.
To get to 1.1.2 firmware, there is additional step that you need which is to run a batch file that you can get from “Conceited Software”:http://conceitedsoftware.com that lets you take vanilla 1.1.2 and jailbreak it (assuming that you are upgrading from a 1.1.1 jailbreak). The exact process is take a 1.1.1 vanilla from the factory, use jailbreakme.com to get to 1.1.1 jailbroken, upgrade to vanilla 1.1.2 and then run the magic batch file to get to 1.1.2 jailbroken. Got it?
Unlocked means that the firmware in the iPhone’s GSM chipset only has been changed so that you can put any SIM card in. Right now, you take 1.1.1 and jailbreak it and then you can install and run a program called AnySim that will unlock the phone. When you jailbreak, you get an iPhone applications called Installer that let’s you install, well just about any third party application.
The web is a little confused right now, but I believe that if you have an iPod Touch you can get to 1.1.2 jailbroken, if you have an Iphone, you have to stay on 1.1.1 because no one has figured out how to jailbreak _and_ unlock a 1.1.2 iPhone. That’s too bad since 1.1.2 apparently have chinese text input which I would dearly love to have!
