DevTeam released PwnageTool 4.2 utility. It is able to create a custom IPSW that can perform an untethered jailbreak on iOS 4.2.1. As usual it can preserve baseband version for unlockers. Devteam used the same method that was implemented in greenpois0n.
PwnageTool supports all 4.2.1 devices other than iPod touch 2G:
The BlackSn0w Unlock utility by Geohot has been updated by MSFTGuy and PushFix to work with the latest firmware 3.1.3. However it works only with baseband 05.11.07 (!!!).
This modified version of BlackSn0w works for iPhones upgraded with PwnageTool or Sn0wbreeze, preserving the baseband version 05.11.07. Users who have updated to OS 3.1.3 by any other method have the 05.12.01 baseband so BlackSn0w and UltraSn0w will not work.
This new version of BlackSn0w will be very useful for iPhone 3GS OS 3.1.3 / Baseband 05.11.07 users who can’t downgrade to earlier versions but still need unlock.
According to iHackintosh, this new version also fixes a small bug making WiFi much more stable.
Blacksn0w RC2 will be available on ModMyi repo soon. If you don’t want to wait just add the source http://cydia.pushfix.info/ to Cydia and install it now.
Important: Blacksn0w for 3.1.3 is still in RC stage and there may be some issues or bugs. This is not an official update performed by Geohot, who has clearly indicated that he will not be updating any tools for the 3.1.3 firmware.
Thanks to and the porting work of as well as the authors of , it is now possible to “tether” your iPhone 3G and use its Internet connection on your laptop.
Warning – Tethering your iPhone is against the iPhone data plan terms. AT&T could slap you with huge fees if you overuse this. I recommend only using it during emergencies.
Here is a basic plan (by the way, this should work for old IPhone also):
The for xpwn 0.3, the firmware 2.0 version of our cross-platform jailbreaking library/command-line utility have been pushed onto . DevTeam tested it on Linux, Windows XP, and Windows Vista for both the iPhone 2G and iPhone 3G thus far, but since it uses the same FirmwareBundles files as PwnageTool, and we know those work for the iPod touch, there ought not be any problems.
Being a suite of command-line utilities, this release is meant primarily for developers. While you can certainly jailbreak (both 3G and first-gen) and unlock (first-gen) with it, it’s not really something you want to try without reading the lengthy, detailed README. If you don’t have the patience to do that, this release is not for you.
For users this news mean that quite soon there will be a new version of winpwn, supporting 2.0.
