iPhone 2G and iPod touch 1G do not officially support iOS 4. However there is a project called WhiteD00r that aims to bring iOS 4 functionality to iPhone 2G users with a custom firmware bundle.
This bundle is created by Matteo Morando and is based on firmware 3.1.3. It is built with PwnageTool. It incorporates several utilities to adds iOS 4 features such as multitasking, wallpaper, tethering, sms count, and more.
There are 3 different versions -- Lite and Full for iPhone 2G and one for iPod touch 1G. Here is the complete feature list:
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.
So this is a minor update, which fixing only the accuracy of the 3GS battery meter and the stability of some third-party app launches. This update is avaliable via iTunes.
New firmware 3.1.3 also introduces a new version of the baseband, the 05.12.01. So if you need unlock do not update! DevTeam also warns us:
If you care about your jailbreak and unlock, don’t update your device – 3G and 3G(S) owners should pay particular attention to this warning.
PwnageTool and redsn0w are not yet compatible with 3.1.3
Experimenters show that the latest version of redsn0w 0.9.2 is able to jailbreak iPhone 2G, iPhone 3G and iPod touch 1G. Just point it at the 3.1.2 IPSW (download here) after doing update or restore to firmware 3.1.3. Sounds like DevTeam will release an updated version of redsn0w that will handle firmware 3.1.3 officially. They say iPod touch 2G with firmware 3.1.3 is also jailbreakable.
Users report that unlock software, blacksn0w and ultrasn0w, doesn;t work with the new baseband.
After days of silence, the DevTeam has finally updated the official blog, writing a little phrase:
Update: We’re currently working on PwnageTool for 3.1, and will be sure to let you know when it’s available!
Good news! PwnageTool is a utility to jailbreak iPhone with a custom created firmware. So what we know for now is that DevTeam is creating a new version of PwnageTool for firmware 3.1. No dates or deadlines as usual. We will keep you updated.
