There is some good news who want an jailbroken iPhone 3G, you can do it now with the latest update to PwnageTool and QuickPwn from the iPhone Dev Blog. However, there is a catch – if you want to have the potential to use soft unlock, you must NOT use QuickPwn – and not use the official updates without using PwnageTool.
As well, it also reports that there is a problem with updating from non-jailbroken phones to being jailbroken. This is because of a “DFU mode” issue. But you can still update Pwned 2.1 to Pwned 2.2 via the Pwnage Tool.
According to the blog post, there seem to have a variety of options to the iPhone 3G being unlocked – and here they are:
SIM Free/SP Unlocked/Factory Unlocked iPhone 3G
This applies if you bought your iPhone 3G for $$$$$$$. 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 2.2 using iTunes and then use QuickPwn to Pwn and Jailbreak. This will add Cydia and Installer too.
Locked iPhone 3G – Preserve Baseband
This applies if you have a locked iPhone 3G and you wish to update to 2.2 but preserve the iPhone’s current baseband software. Preserving the baseband will give you the maximum chance for any upcoming software unlock. To upgrade your phone to 2.2 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.
There are plenty of tutorials about this process on the web, but PwnageTool contains intuitive graphics and easy to follow prompts that should have you up and running in no time at all. Please note: PwnageTool is only available for Mac OS X.
Locked iPhone 3G
If you are using your iPhone with one carrier and have no interest in the possibility of an iPhone 3G unlock in the near future then just restore or upgrade to 2.2 using iTunes and use QuickPwn to Jailbreak and add Cydia and Installer.
Meanwhile, for the iPod touch – the second generation has not been able to be unlocked, so you might as well wait – or get an iPhone and if you screw up the Pwnage, you can still have the iPod touch (just without the phone bit).
