Troubleshooting

The Corona 5.0.1 Untether package has received another update, this time to correct an iBooks problem where images failed to display or displayed incorrectly after installation. Chronic Dev Team released Corona 5.0.1 Untether to free tethered jailbroken devices including the iPhone 4 from the need to reboot with a computer.

After installing early releases of both Corona and the redsn0w jailbreak for iPhone 4 and 3GS devices, some users had problems with iBooks including a Configuration Error dialog. The latest version of Corona (1.0-7) should fix both iBooks errors and can be installed directly from Cydia on a jailbroken device.

Some iPhone 4S users are experiencing a strange, involuntary mute when dialing out using their mobile devices. The problem is that the person dialing out can't hear anything on the other end of the line, not even a ringing phone. People receiving the calls can hear the iPhone 4S owner just fine. An Apple discussion page titled Outgoing call no audio started almost immediately after the iPhone 4S was released and has leap over to additional discussions.

Although Apple was quick to respond to complaints about iPhone 4S battery life being shorter than expected, there's no official word on whether or not a fix is in the works for the audio issue. Some iPhone owners who experienced the problem were able to correct the issue with a full restore. Others who have not had luck fixing the problem have begun to call the issue Audiogate.

UPDATE: iPhone developer pod2g blogged that an upcoming Corona update will fix "iBooks and other softwares having sandbox issues." We will let you know when it's released.

When jailbreaking iOS there are sometimes caveats and unintended consequences, although normally for enthusiasts the advantages of running new software take precedence. iBooks fans might have found that after liberating their device with the latest redsn0w untethered iOS 5.0.1 jailbreak that iBooks ceases to work.

Now there's a package available in Cydia that should fix the problem. Some users have reported no luck with the fix, but our team was able to fix iBooks using the procedure below. As always, jailbreaking and installing non-Apple packages is performed on your iPhone at your own risk! Here are instructions to fix iBooks after jailbreaking.
