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?

Those devices such as iPhone 3GS iPhone 4 iPod Touch 3G require SHSH Blobs to install firmware.Apple distributes SHSH Blobs with the original firmware so it can be installed. The way SHSH Blobs is being computated has not been found yet so there is no untethered custom firmware on newer bootrom devices.Tethered custom firmware only work on a pwned iBoot.
