Just days after the iPhone Dev Team released untethered jailbreak utilities for iOS 4.3.1, Apple went and released iOS 4.3.2 today. Among other things, the update patched some security holes in the mobile operating system — which means that you need to get creative if you want to re-jailbreak your iPhone, iPod touch, or iPad after updating to iOS 4.3.2.
Fortunately the folks at Redmond Pie have put together a guide showing how to perform a tethered jailbreak.
Update: It looks like you can also use the same tools to jailbreak iOS 4.3.2 as you use for iOS 4.3.1. The tricky thing is you’ll need to use the 4.3.1 IPSW and the result is still a tethered jailbreak instead of untethered.
The difference between tethered and untethered is whether the jailbreak survives a reboot. Since this is a tethered jailbreak method you’ll have to connect your phone to a computer every time you power it down and back up again or you’ll lose your jailbreak. Fortunately iOS devices are pretty stable and I regularly go weeks or longer without rebooting my iPod touch.
The latest jailbreak requires the latest version of the PwnageTool, the iOS 4.3.2 software, and a computer running OS X. The process is also a bit complicated at the moment, so if you’re looking for an easy solution you may want to wait for the iPhone Dev Team to release an updated version of redsn0w.
There’s currently no way to unlock a phone running iOS 4.3.2, so if you need to unlock your iPhone to work with a different wireless carrier, you should avoid updating to iOS 4.3.2 at all.
