Flipping between landscape and portrait mode on the iPhone can be useful, or it can be detrimental to getting things done. Locking the screen orientation in iOS is a simple proposition, however there are some apps where one mode is almost always better than the other. So why not automatically switch when needed?

Using the stock iOS calculator in landscape mode provides many scientific functions beyond the extremely simple portrait mode numerical calculator. If you're interested in only using the scientific calculator the tweak LandscapeCalc will automatically switch the calculator app into this mode. Once installed on a jailbroken iOS device, there are no settings to configure.

Universal Uclick's GoComics app brings the Sunday funnies to your iOS, Android or mobile Windows device. The app is updated daily with the world's most popular comic strips, and offers a vast collection of back issues so you'll never be short on reading material. The app also features all the standard social media sharing options, and a comics blog so you can stay updated on the latest news.

The "New Comics" section highlights upcoming cartoonists like Geoff Grogan (Plastic Babyheads from Outer Space), and the "Popular Comics" section features such classics as Calvin and Hobbes and Dilbert. You can even use the calendar option to jump back in time to see how comics like The Boondocks became a cult classic.

Some of the best jailbreak tweaks provide useful information in a sleek and stylish manner, improving on stock iOS features. One such tweak is Live Battery Indicator, which merges the best of both worlds when it comes to showing battery life remaining. Not only will the new status bar icon displayed by this tweak show current battery percentage, but it will graphically show how much power is left.

A simple circle surrounding the percentage indicates this value visually, so as the battery power is depleted the circle indicates life remaining. When battery life is low, the circle will be proportionally dark to indicate that charging is needed. Unlike the stock iOS battery icon with percentage turned on, Live Battery Indicator is compact, saving space and displaying information efficiently.

When it comes to the iPhone camera, the hardware has remained basically the same since the iPhone 4S launch. That's set to change based on information from a credible report detailing the next generation camera to be featured on the iPhone 5S. Tinhte.vn claims its sources at Wonderful Saigon Electrics have the inside scoop on new camera modules they're manufacturing for Apple.

A jump in resolution from the current eight megapixel CMOS image sensor to a 13 megapixel version on the iPhone 5S will be a significant change. Besides higher resolution, the new cameras are said to have better low light performance for improved night shooting. This could be an important distinction for Apple, considering smartphone and camera manufacturers alike are striving to compete on this front.

It goes without saying that mysterious photo leaks from anonymous sources can't always be trusted. Apple itself has been known to develop and test several prototypes before deciding which model to put into production for the masses, so even legitimate leaks don't mean much. Even so, Tactus claims this photo depicts the back of the upcoming budget iPhone coming later this year.

Analysts and the rumor mill have been talking about a less expensive iPhone model for some time, which would presumably make it possible for Apple to further increase the market share of the handset. Not only could a cheaper iPhone make the device more accessible to more people, it would certainly lower production costs for Apple while introducing the App Store and iTunes to more paying customers.
