ih8sn0w teases iBooks on Jailbroken iOS5 (Video)
*Update* Now there is a working iOS5 iBooks fix via SSH/iFile
One of the downfalls of the current iOS5 tethered jailbreak is that iBooks does not work once jailbroken. @ih8sn0w the creator of sn0wbreeze has teased a YouTube video(see below) of iBooks running a jailbroken iOS5 device.
According to ih8sn0w, the issue is because of how redsn0w and sn0wbreeze performed sandbox patches in the kernel. Sandbox is a security measure that is used to ensure applications such as Safari don't have access to personal information or system files.
Unfortunately, he goes on to say that he will not be releasing the fix. Apparently the fix is unstable and he does not feel comfortable releasing it, however, hopefully this will inspire someone else to release a fix or maybe he will decide to improve on it so that he can release it to the public. Until then, jailbreakers will still have to go without iBooks.
