When the iPhone 4 and iOS 4.0 was
released, the Dev Team was able to relatively easily develop a
browser-based
jailbreak using JailbreakMe.com. The jailbreak made use of an
vulnerability in the way that Mobile Safari handled PDF documents.
Now, just hours after the official
iOS 4.1 ipsw was posted to Apple's servers, the Dev Team has
discovered a bootrom exploit that will used in the iOS 4.1 jailbreak.
The Dev Team's Musclenerd tweeted,
"Crazy timing that @pod2g got latest exploit just as 4.1 went
public (lots of work left…keep away from 4.1 for now!)."
According
to Redmond Pie, this exploit won't be something that Apple
will
be able to patch as quickly as the previous PDF exploit:
Also, the best
thing about a low-level bootrom exploit is that Apple wont be able to
patch it simply by releasing a new firmware update. Instead, it will
require Apple to release a revised hardware version of iPhone 4,
iPhone 3GS, iPad and the iPod touches with new bootroms in order to
patch the bootrom exploit.
This is good news for iPhone 4 users
that want the fixes included in the iOS 4.1 update (proximity sensor,
Bluetooth connection issues), while at the same time providing access
to the wealth of "underground apps" and customizations that
can be had with unauthorized app stores like Cydia.
You'll just have to be patient as the
Dev Team works its magic to complete work on the iOS 4.1 jailbreak.
