iPhone Dev-Team Releases Unofficial PwnageTool Bundle for iPhone 3GS

Posted by · 37784 views · Translate
The iPhone Dev-Team has released an unofficial PwnageTool bundle for iPhone 3GS owners with the old bootrom that want to update to iOS 4.2.1 without upgrading their baseband.

For those Mac users with an old-bootrom 3GS who really know what they’re doing, here’s a minimal 3GS 4.2.1 bundle that will get you to 4.2.1 without updating your baseband. Be sure to uncheck "Activate the iPhone" using Expert mode. To actually jailbreak after you’ve restored with the help of that bundle, please use redsn0w. If you don’t know how to drop a bundle into PwnageTool.app, please hold off on 4.2.1 until it’s untethered for everyone

You can find a tutorial on how to install this firmware bundle here.

I understand the whole part of creating a custom IPSW to keep my old BB. However, I want to use this on T-Mobile network (in USA). Do I still uncheck \"Activate\"? Thanks for the guides! They\'re really helpful to read through before actually attempting the process.

(so eventhough the phone is already jailbroken, i need to jailbreak again?) 5. make sure to uncheck install ipad baseband (right?) 6. using cydia, download and use ultrasnow to unlock? are these steps correct? will i be able to run 4.2.1 on my 3gs while keeping the 5.13.4 bb? just wanted to make sure, i know exactly what to de before i even try.

Once a custom firmware is created and restored without upgrading the baseband, and using redsn0w to jailbreak, wouldn\'t redsn0w upgrade the baseband? I thought 4.2.1 required the newest baseband to even boot? Anyone jailbreak to 4.2.1 without upgrading baseband? I\'ve got a 3gs with 05.12.01. Thanks.
