IREB

A program created by iH8sn0w, that is used for early-generation devices, which include:

• iPhone 3G
• iPod touch 2G (old bootrom)

What is iREB?

iREB is a GUI application that uses iTunnel. It uploads 3 pwned files, so that iTunes can accept custom IPSW firmware/downgrade to lower firmwares. For S5L8900 devices, it uploads the following:

• iBSS.MODEL.RELEASE.dfu
• WTF.MODEL.RELEASE.dfu
• WTF.s5l8900xall.RELEASE.dfu

iREB does NOT jailbreak, it just disables iTunes's ability to upload a patch to the ramdisk to block custom firmware made by sn0wbreeze.

Why cant it work with the later-generation devices?

It will be supported soon as there is a bootrom exploit available to upload iBSS but it will be a tethered boot.[1]
