Jailbreakme.com 3.0 compatibil cu iOS 5, functioneaza cu unionfs


Impreuna cu noua solutie de jailbreak numita jailbreakme.com 3.0 a aparut pe blogul Dev Team si un articol in care ne sunt explicate cateva lucruri despre munca depusa de comex pana acum. Dev Team ne spune ca solutia aceasta de jailbreak ar putea fi folosita si pentru versiunile beta ale iOS 5 insa probabil Apple va inchide exploitul pana la lansarea versiunii finale. Tot de la Dev Team aflam ca in jailbreakme.com 3.0 comex a reusit sa implementeze unionfs, o tehnica prin care viteza de implementare a jailbreak-ului este dramatic imbunatatita si daca ati facut deja jailbreak ati observat cat de rapid s-a desfasurat intregul proces si nu a fost nevoie nici macar de restart. Dev Team avertizeaza utilizatorii sa faca backup datelor din terminale deoarece este posibil ca unionfs sa afecteze informatiile din iDevices deci ar fi bine sa le ascultati sfatul.

In final jailbreakme.com 3.0 poate fi rulat peste versiunile vechi ale redsn0w, PwnageTool sau sn0wbreeze insa nu veti avea nimic de castigat din asta. Daca aveti jailbreak ramaneti cu ce aveti pentru ca aplicarea altuia peste cel existent nu va schimba mai nimic. Cam atat de la Dev Team, happy jailbreaking!

Q: Which devices and firmware versions are supported?

A: In this initial release, the following configurations are supported:

  • iPad1: 4.3 through 4.3.3
  • iPad2: 4.3.3
  • iPhoneGS: 4.3 through 4.3.3
  • iPhone4: 4.3 through 4.3.3
  • iPhone4-CDMA: 4.2.6 through 4.2.8
  • iPod touch 3g: 4.3, 4.3.2, 4.3.3
  • iPod touch 4g: 4.3 through 4.3.3

Q: How does jbme3.0 differ from the existing jailbreaks?

A: jbme3.0 is entirely userland-based, from start to finish.  The A5 chip in the iPad2 has no iBoot or bootrom-level exploits yet, so tools like redsn0w, PwnageTool and sn0wbreeze can’t use the limera1n bootrom exploit to inject the jailbreak.  Even for those devices where limera1n works, jbme3.0 injects the jailbreak with a userland exploit.

Q: If I’m already jailbroken on the latest firmware, is there any advantage to jailbreaking again?

A: No, but you should consider showing this to your friends!  Spread the jailbreaking fever.

Q: Are the holes exploited by jbme3.0 closed in iOS5?

A: The holes still exist in the iOS5 betas, but they’ll almost certainly be fixed by the time iOS5 is public.  However because the iPad2 had no public jailbreak yet, it probably wasn’t worth waiting until the fall to use them.  If history repeats itself though, there will be more holes and exploits.

Q: Will I permanently lose the jailbreak if I need to restore my device?

A: For all except the iPad2, saving your SHSH blobs should let you always restore your device to iOS versions where this jailbreak works.  The iPad2 is a little more complicated.  If you have a wifi-only iPad2 and saved SHSH blobs, you’re in good shape.  But if you have the GSM or CDMA iPad2, you won’t be able to restore to 4.3.3 or lower once Apple stops signing its baseband.  There are a few ideas that might work to get around this limitation, but for now it’s best to assume there’s no going back to 4.3.3 once 4.3.4 is out for iPad2 GSM or CDMA owners.

Q: I heard this new unionfs stuff is dangerous?

A: Define dangerous 🙂  Seriously though, although unionfs is a huge improvement to the install time of the jailbreak, it is brand new code and there is the possibility something will go wrong.  Just keep regular backups of your media and content and you should be fine.  If there are any problems, they should appear within the first few days, so hold off and let “everyone else” test the waters if you’d like.
