Jailbreak iPhone, iPod Touch, iPad

Next iPhone/iPod/iPad firmare iOS 4.2 is due out soon. What can we expect in terms of jailbreaking 4.2?

Limera1n exploit for 4.2 in most cases is a tethered jailbreak. That means if you have to reboot your device, it will show a “connect to itunes” logo until you run the jailbreak software again.

• iPhone 3G – will run 4.2 untethered. Redsn0w will be updated.
• iPhone 3GS – old bootrom will run 4.2 untethered if done via Pwnagetool while updating from 4.1. Otherwise it will be tethered.
• iPhone 4 – tethered
• iPod 2G – untethered.
• iPod Touch 3G, iPod Touch 4G – tethered
• iPad – tethered.

Tethered jailbreak isn’t that bad for iPads and iPods. But if something happens and your iphone reboots while you’re away from your computer, you cant use the device until you get home and run some tool on your computer again.

We suggest not updating until new expoit will be implemented in new utility.

The community is working on a solution to this to either make the jailbreak untethered or at least semi-tethered. Semi-tethered means the device will at least reboot, but unjailbroken while on the road until you return to your computer.

Multiple developers and users testing out the iOS 4.2 betas claim that the AirPlay functionality was definitely removed from Apple’s iPhone 3G. AirPlay is gone from the golden master version of iOS 4.2. In fact, the AirPlay did work on the iPhone 3G at the previous betas. There are no any reasonable causes why the AirPlay was cut from the GM version.  Perhaps, Apple is trying to get users to upgrade to their latest iPhone model or, on the other hand, it is just an issue in the GM seed. May be the AirPlay functionality will return in iOS 4.2 public release. Anyway, there will undoubtedly be a jailbreak that can re-enable it.
