Apple stopped to support original iPhone 2G and iPod touch 1G starting from iOS 4.0. Their decision was justified because of the low RAM and sow CPU in these first-gen devices released back in 2007.
iPhone jailbreak community has now come up with a mod, which brings the complete look and feel of iOS 4.2.1 for iPhone 2G, 3G and iPod touch 1G and 2G. The mod is basically based on the iPhone OS 3.1.3, to replicate the experience of iOS 4 on the first and second generation iPhone and iPod touch.
This custom firmware, named WhiteD00r, includes everything from iOS 4.x: wallpapers, new semi transparent dock (and UI), backgrounds, all new icons from iOS 4.x, Voice Control, multitasking, video recording, and more. Full list of features can be found here.
Moreover WhiteD00r was also relased for iPhone 3G and iPod touch 2G. Regular iOS 4.х works really slow, on these devices, while modified 3.1.3 has much more chances.
WhiteD00r custom 4.2.1 firmware for iPhone 2G, iPhone 3G, iPod touch 1G and iPod touch 2G can be downloaded from here.
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 iPhone Dev-Team has released PwnageTool 3.1.5 for Mac OS X. It allows iPhone and iPod Touch users to safely upgrade to firmware 3.1.3. With PwnageTool you can preserve jailbreak and ultrasn0w unlock. But if you’re using the blacksn0w unlock with baseband 05.11.07 you will need to stay at firmware 3.1.2.
PwnageTool 3.1.5 creates a custom 3.1.3 IPSW for the following devices:
iPhone 3GS with early bootrom
iPod touch 1G
iPod touch 2G with early bootrom
Warning! Don't try to use this tool if you have iPhone 3GS with firmware 3.1.3 - it just won't work. If you have iPod Touch 1G, iPhone 2G or factory unlocked iPhone 3G , try to use redsn0w - is would be much easier.
H8sn0w has just released the new version of Sn0wbreeze 1.4. Sn0wbreeze is a jailbreak utility with functionality similar to PwnageTool. The new version supports firmware 3.1.3 jailbreak for the following devices:
Sn0wbreeze is a Windows application, so Mac users have to wait for the upcoming release of PwnageTool by the DevTeam. Alternatively, both Mac and Windows users can use Redsn0w to run jailbreak (no custom firmware though).
You can download the new version of sn0wbreeze here.
MuscleNerd continues to argue that we should not use sn0wbreeze. Especially users who have unlocked their iPhone with blacksn0w utility:
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.
iH8Sn0w has released a beta of Sn0wbreeze a software utility which jailbreaks the iPod Touch 1G, 2G and iPhone 2G, 3G, and 3GS (old bootrom & non MC). The software runs on Windows XP, Vista, 7 (32 or 64 bit). Sn0wbreeze is similar to PwnageTool for Mac. It will allow you to create custom ipsws which can be built to include Cydiaapplications and personalized boot logos.
At this time BlackRa1n is still recommended for Windows users with firmware 3.1.2 and RedSn0w for earlier firmwares.
DevTeam just released PwnageTool 3.1.4. It allows users to jailbreak firmware 3.1.2 on iPhone 2G/3G/3GS and iPod Touch 1G/2G. It also supports OTB iPhone 3GS with firmware 3.1.x. We remind you that if you need unlock, do not update on regular 3.1.x firmware, use Pwnagetool to create custom firmware to preserve old baseband.
Here is a quick howto:
Factory Unlocked iPhone 3G and iPhone 3GS: You do not need unlock, just use PwnageTool to create an ipsw and then use this to update and jailbreak your phone.
iPhone 3G and iPhone 3GS: if you need unlock, use PwnageTool to create a custom firmware with an old baseband. Then update using created custom firmware and install ultrasw0w via Cydia to unlock.
iPhone 2G: Use PwnageTool to do the magic and then restore with iTunes using your newly created .ipsw.The baseband will be unlocked, the phone jailbroken.
iPod Touch 1G: Use PwnageTool to create a firmware image and restore with that .ipsw using iTunes.
iPod Touch 2G: You must already be jailbroken in order to use PwnageTool. If so, create a firmware image and restore with that .ipsw using iTunes.
The DevTeam has just released Pwnage Tool 3.1-3, the new version of the tool for Mac OS that lets you run the jailbreak on iPhones and iPod Touch with firmware 3.1. The new version adds limited support for iPhone 3GS and iPod Touch 2G. It still works with iPhone 2G (EDGE), iPhone 3G and iPod Touch 1G.
The iPhone 3GS is now supported in PwnageTool 3.1.3,assuming the phone was pwned at 3.0 or 3.0.1 - PwnageTool does not support the 3GS out of the box. If your iPhone 3GS has 3.1 preinstalled and is not Pwned then there is no tested jailbreak solution at the moment.
The iPod 2G is now supported in PwnageTool 3.1.3, assuming the iPod 2G was pwned at 3.0 or 3.0.1 - PwnageTool does not support the iPod 2G with 3.1 softwareout of the box.
DevTeam released PwnageTool 3.1. This utility will allow users of iPhone 2G, iPhone 3G, iPod Touch to run jailbreaked firmware 3.1. We still recommend staying on firmware 3.0/3.0.1 for as long as possible. The 3.1 firmware is not worth it. But if you really want 3.1. Here are the details:
If you are using a 3G iPhone with ultrasn0w and rely on ultrasn0w to obtain cellular service, then you should only upgrade to 3.1 with a PwnageTool created .ipsw. Never update using Apple's unmodified firmware. Stay away from Apple’s direct updates.
This version of PwnageTool WILL NOT work for the iPhone 3GS and iPod Touch 2G/3G.
PwnageTool WILL work for Original iPhone (1st Generation), Original iPod touch (1st Generation) and the iPhone 3G.
It works only with Mac OS X.
Future releases of PwnageTool and RedSn0w will be soon with more functionality.
Here is per device info:
iPhone 3G (unlocked): This model of iPhone 3G doesn’t have an Service Provider lock (aka factory unlocked) and you are able to put any SIM card into the phone and get service. Your phone is already unlocked so you do not need to worry about baseband updates, simply upgrade to 3.1 using iTunes and then use PwnageTool to create an ipsw and then use this to jailbreak your phone.
iPhone 3G (locked): You need to preserve 3.0 baseband. Create a custom firmware.
iPhone 2G (1st Generation): Use PwnageTool to do the magic and then restore with iTunes using your newly created .ipsw, you don’t need to worry about anything, the baseband will be unlocked, the phone jailbroken.
iPod touch 1G (Original iPod Touch): Use PwnageTool to create a firmware image and restore with that .ipsw using iTunes.
iPod touch 2G: Sorry, no support at this time within PwnageTool, use Redsn0w for an earlier (pre 3.1) firmware release instead.
iPod touch 3G (New iPod Touch): Sorry, no support at this time within PwnageTool.
