iPhone 2.2: what you need to know if you want to Jailbreak

Baseband 101

The ‘baseband’ is the generic name given to the internal components of the iPhone that handle the phone calls and Internet access. This ‘baseband’ is a tiny and unique independent computer system that runs inside your iPhone, it is separate to the main system that handles the applications (such as email and google maps) and it talks to the main part of the phone over an internal communications network. Think of it like a cable modem or other peripheral that is attached to your home PC that needs occasional updates. When a software update is released and presented to you within iTunes the baseband is sometimes updated (to fix bugs or add new features). The 2.2 update for the iPhone 3G contains such an update, so running the vanilla updater straight away with iTunes will reprogram and update the baseband. This could be bad for certain people, depending on your ultimate aim.

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.

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.

iPhone 2G (1st Generation)

Restore your iPhone 2G with iTunes then run QuickPwn to do the magic, ‘nuff said.

iPod Touch 1G (Original iPod Touch)

Update to 2.2 with iTunes and run QuickPwn.

iPod Touch 2G (New iPod Touch)
