Comex has just released, again via Twitter, new details about his next tools to run the jailbreak firmware 4.2.1 on all untethered devices.
It could be a simple program to download and install devices on already released (tethered) with the latest version of Redsn0w released by the Dev Team.
In the message published by the author [Comex] of Spirit and JailbreakMe reads:
It will, probably, a package for Cydia. Also if I can make it work.
As explained by the same Comex tweet in a second, references to the next tool to jailbreak are quite clear and obvious.
The jailbreak of the Comex, in contrast to the "backup plan" of the Dev Team does not require the use of blob SHSH firmware 4.2 beta 3. According to the developer, the likely new package will be released in Cydia soon be completed and has been tested for proper operation.
The tool in question will almost certainly be compatible with all devices A4 (fourth iPhone, iPod Touch 4G, iPad, Apple TV2) and even with previous generation devices. At the moment no further details.
We will keep you updated.
