Apple's universal reader app for iPhone, iPad and iPod touch has just been updated to version 1.5. The new iBooks adds several new features including a nighttime reading theme to ease eye strain when reading in a dark room. Some studies have shown that viewing LCD screens before bedtime can keep some people from falling asleep quickly. Maybe the new iBooks will help.

Apple has also added several new fonts including Athelas, Charter, Iowa, and Seravek for your reading pleasure. For those who may have been irritated by the book-like graphics that take screen real estate away from the text, Apple has added a full-screen mode to remove distractions.

If installing full Siri functionality on the iPhone 4 sounds too good to be true, that's because it is. A new software package claiming to make Siri run on a jailbroken iPhone 4 has appeared on a repository that Cydia warns against. The package is called H1Siri, and there are a few reasons why you should stay away.

Not only does the repository containing H1Siri contain cracks and other illegal software, but the package itself comes from an unknown developer. Apparently a Chinese group dubbed CD-Dev Team is behind the Siri port, but the software illegally uses parts of Apple's copyrighted code.

Apple isn't playing nice with the jailbreaking community and has recently started blocking devices from restoring to older firmware. If you accidently updated to 5.0.1 and want to restore your device, hacker iH8sn0w has a new solution for you. iFaith v1.4 allows you to save your iOS device’s SHSH blobs which should allow you to downgrade your device in the future.

Unfortunately it doesn't support A5 devices. Meaning if you recently purchased an iPhone 4S, or upgraded to iOS 5.0.1, you're still out of luck for now. A4 owners are being urged by the jailbreaking community to download the latest update of iFaith and to save their SHSH blobs immediately.

Battery cases make great accessories for the iPhone and iPod touch. Not only do they protect the mobile device, but they increase the battery life, often doubling battery power and keeping the iPhone charged. There are always sporadic reports of lithium-ion batteries malfunctioning, which can involve excessive heat, fire or even explosions.

Lately two brands of iPhone battery cases have been recalled as problems with internal parts have been discovered. To avoid risks of overheating and possible fire, use of these cases should be discontinued immediately. The first recall involves the Rocketfish RF-KL12, designed for the iPhone 3G and iPhone 3GS.

Two popular zombie games have made their way to the Apple App Store this week. Activision released the popular Call of Duty: Black Ops Zombies, and developers Digital Chocolate have made their Facebook hit Zombie Lane available on the iPhone and iPad. The newest Call of Duty app is $6.99, and offers 50 levels of zombie killing madness. You can play solo or on teams of four via Call of Duty’s new interface which features Voice Chat for the first time ever. There is also a new unlockable arcade-style top-down shooter mode called "Dead Ops Arcade" with Game Center leaderboard support.

Zombie Lane is free in the iTunes App Store, but it's one of those annoying Facebook type games that forces you to pay for upgrades. You're tasked with rebuilding your neighborhood by smashing and shooting the undead, rebuilding fences and growing crops. There are plenty of missions to complete, achievements to gain and extra things to do if you're willing to pay real money for the honor of doing so. If you're not willing to shell out the cash, you will find yourself standing around a lot unable to perform any tasks.
