The Dev Team has done it again. Yesterday they released updated versions of their PwnageTool and QuickPwn. Both have been updated to 2.2.5, to jailbreak the latest iPhone firmware 2.2.1.
QuickPwn 2.2.5 has been updated for both Mac and Windows.
PwnageTool 2.2.5 remains Mac only at the moment.
This time around, Apple tried to remove the yellowsn0w unlock with their 2.2.1 firmware update. So if you update your iPhone 3G directly within iTunes, your baseband will change since 2.2.1 firmware has a new baseband update.
Q: SO…what to do if you’re using an iPhone 3G and want to update to 2.2.1, but KEEP your iPhone unlocked?
A: You will have to update via a “custom firmware”, which PwnageTool 2.2.5 will do for you. Essentially you’ll create a 2.2.1 firmware file with the old 2.2 baseband (are you confused yet?).
Q: What about unlocked iPhone first gen users who want to update to 2.2.1? Will I lose my unlock?
A: No. Just update to 2.2.1 in iTunes, then use QuickPwn to jailbreak/unlock. The baseband has not changed.
Q: I’m using a late 2008 MacBook. What about my DFU problems?
A: Use a USB hub and it will work fine. That’s what I did for my update to 2.2 a while back.
Q: Is this 2.2.1 update worth it?
A: It’s up to you. It’s relatively minor, so unless you’re lazy and don’t want to tinker around (yet again), just hold off. There’s nothing new and you can save yourself some trouble. As for the rest of us…
Baseband 101 (from the Dev Team)
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 2.2.1 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.
Who here has updated to 2.2.1? I’m going to give it a shot, I will report back shortly. 😉
