Apple's e-reader app iBooks received an update last week, boasting a fairly typical set of changes: better stability, better layout, and a connection to AirPrint. But according to some reports, this latest version can cause problems for those trying to open e-books on jailbroken iPhones. According to Social Apples, the iBooks app will no longer launch on a jailbroken phone: "Today marks a new realization for me as a jailbreaker: Apple deliberately crippled my device." Sponsor That might sound a little melodramatic, but for those who have paid for books via iBooks and have jailbroken their phones, it's more than a little frustrating.
