DevTeam hacker MuscleNerd tweeted that they after releasing redsn0w jailbreak for 4.2 the team can start working on iPhone unlock. Users can expect the unlock for the iPhone 3G and iPhone 3GS this week. The iPhone 4 unlock will take more time and no concrete info is available about that yet.
The ultrasn0w unlock will be released for iOS 4.1 firmware. So is you need unlock, do not update to iOS 4.2.1.
Hacker MuscleNerd has tweeted that the DevTeam plans to release PwnageTool for iOS 4.1 in several days.
For AppleTV 2G users, the goal is for PwnageTool to cover you by Funday/Sunday (but still very limited app capability)
This release should also bring jailbreak for iPod touch and iPad Mac users.
PwnageTool is a Mac OS X jailbreak tool. One of it's advantages is the ability to preserve old baseband, which means you can have firmware iOS 4.1 with baseband from iOS 4.0 (if you haven't updated to 4.1 already). And this brings unlcok, because iOS 4.0 is unlockable.
Sherif Hashim has discovered an exploit which may allow unlock of the latest iPhone OS 3.1.3 baseband 05.12.01. Such unlock utilities for previous baseband versions were called blacksn0w, ultrasn0w и and yellowsn0w. MuscleNerd, the member of DevTeam, has already confirmed it is working. So the timing of the unlcok release is totally up to them right now.
Here is an official update from DevTeam:
"We’ve started to look at his crash but it’s a long road between any given crash and a fully working unlock, and we couldn’t put an ETA on it even if we wanted to. It’s not even guaranteed that an working unlock will come from this particular crash — it’s just too early to tell."
Yes, DevTeam released new version of their software. First of all, please, do NOT use unofficial software from unknows sites (f.e. quickpwm.com). We recommend to download from torrent or official mirors.
We regulary publish latets software and firmware links. Use them or the same ones from DevTeam site.
iPhone 3G + NO UNLOCK: If you do not need unlock, you are using your iPhone with one carrier or you hae factory unlcoked iPhone, just restore or upgrade to 2.2.1 using iTunes and use QuickPwn to jailbreak and add Cydia and Installer.
iPhone 3G + UNLOCK: you need to preserve current baseband software. Preserving the baseband will ensure that you can still use “yellowsn0w” the iPhone 3G unlock application. To upgrade your phone to 2.2.1 and preserve the state of the baseband you need to create a custom .ipsw with PwnageTool. This custom .ipsw will not contain the baseband update but of course will still allow all the cool new stuff from 2.2.1. PwnageTool is only available for Mac OS X.
DevTeam updated yellowsn0w to version 0.9.7 to work with modified (!!!) firmware 2.2.1, in which you preserve old baseband from firmware 2.2.
