Update available to jailbreak latest firmware

The ingenious people at iPhone DevTeam have released QuickPwn and Pwnage Tool to jailbreak the latest version of the firmware (2.2). How should you jailbreak your iPhone? It depends.

SingTel's iPhones

If you bought your iPhone from SingTel, jailbreaking is straightforward. This is because your iPhone is already unlocked, ie, you can put any SIM card into the phone and it will work. To upgrade, they say, simply "upgrade to 2.2 using iTunes and then use QuickPwn to Pwn and Jailbreak. This will add Cydia and Installer too."

Grey market iPhone 2Gs

If you have a grey market iPhone 2G (the original ones), also no problem. According to the blog post, just "Update or Restore your iPhone 2G with iTunes then run QuickPwn to do the magic, ‘nuff said, you don’t need to worry about anything."

Locked iPhone 3G

Things get complicated if you have a locked iPhone 3G, meaning it can only be used on one carrier. This happens in markets where Apple has an exclusive deal with the carrier and the regulator allows locked sets. (In Singapore, SingTel has exclusive distribution but the regulator does not allow locked sets). 

If you don't care about using the iPhone on another carrier, then, it's pretty easy. "Just restore or upgrade to 2.2 using iTunes and use QuickPwn to Jailbreak and add Cydia and Installer."

If you do want to unlock your iPhone (i.e. use it on another carrier) at some point, they say:

 "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."

I have to confess I barely understand this and I'm certainly not recommending a jailbreak to anyone. This information is provided for people who might need it.
