For those enjoying digital tome via the jailbreak iBookstore, Apple seems to have enforced some restrictions in its iBooks e-book reader app. From iBooks version 1.2.1 on, the app thew in an improperly signed binary before opening a DRM-protected book. If the device executed the binary, the app concluded the device is jailbroken and displays this ambiguous error:

''There is a problem with the configuration of your iPhone. Please restore with iTunes and reinstall iBooks.''

Now the iPhone Dev Team has released an update to its Pwnage Tool that include a fix for the iBooks issue. This means iPhone unlockers can safely restore to a custom 4.2.1 pre-jailbroken IPSW and retain their current baseband and unlock. PwnageTool also supports all the other 4.2.1 devices other than iPod touch 2G:

  • iPhone3G
  • iPhone3GS
  • iPhone4
  • iPhone4-Verizon
  • iPod touch 3G
  • iPod touch 4G
  • iPad
  • AppleTV 2G

PwnageTool also includes two very recent improvements to the 4.2.1 JB: iBooks was just fixed by @comex and @pushfix last night so that it works as intended on DRMed books, and the wifi problem on AppleTV 2G was fixed. Both of these fixes will also be available in upcoming Cydia package updates, so if you're already jailbroken you can wait for those updates rather than restore and jailbreak again.

The iPhone Dev Team also pointed out that the typical lag time between a new iOS release and a new jailbreak may not be as long in the case of iOS 4.3, expected to be released within weeks, if not sooner.

Security researcher Stefan Esser hinted via Twitter that he had an untethered iOS 4.3 jailbreak ready to roll.
