MiPow offers a pair of battery cases for the iPhone 4 and 4S--the $79 Maca Air and the $79 Maca 2200 Color Power Case. The two cases are very similar: Each sports a transparent top cover and edging--in fact, the top plastic caps are interchangeable between the two models. Each case ships with two such caps, so you have a backup in case you lose one. The back of each case is anodized metal that reflects trippy patterns in light, and multiple colors are available.

Nokia is betting its future on Microsoft’s mobile OS, and on Wednesday introduced its first Windows Phone 7 device, the Lumia 800. If the Lumia 800 looks familiar, that’s because it’s similar to the Nokia N9, which runs OS (MeeGo) soon to be ditched. The Lumia 800 brings a few improvements over its relegated sibling, including a faster processor, but compared to the big boys, the iPhone 4S and the latest Android Galaxy Nexus and Droid RAZR,

It seems like every time a major software revision comes along, it’s described as the “biggest ever.” In the case of iOS 5, though, that might not be hyperbole—there’s hardly a part of Apple’s mobile operating system that isn’t altered in some way by the latest update.

I approach iOS-ified versions of classic arcade and console games with a healthy mixture of anticipation and trepidation. On the one hand, it's nice to see all those games I wasted all those hours playing in my misspent youth making an appearance in my slightly less misspent adulthood. On the other hand, the graphics and gameplay of two or three decades ago doesn't always translate well to Apple's state-of-the-art handhelds.

Because it takes such amazing pictures, the iPhone 4 has become the pocket camera of choice for many users--myself included. The phone's built-in camera is easy to use and always handy. What's more, the App Store is loaded with a number of great third-party apps to help you make the most of your photos. And many of these filters will cost you very little--or nothing at all.

I only recently reviewed Capcom's iOS port of Dead Rising, and here I am with yet another game starring the undead, albeit a very different one. In a game market that has been bombarded with all kinds of zombie-themed action, Stupid Zombies by GameResort is a straightforward, clean, and--dare I say it--adorable puzzle game for the iOS.

The world of iOS-based GPS navigation apps has matured since we last reviewed this category, and the situation has improved. These apps are designed to mimic standalone navigation hardware, those dash-mounted or in-dash devices that guide you to a destination, navigating with the aid of visual cues and maps and often complemented with spoken directions and street names. Both standalone devices and iOS apps can integrate live traffic information for alerts and active rerouting, too.

Microsoft has a very slick device, but it can't do nearly as much as the iPhone -- especially in business

If you're the kind of person who likes to waste their iPhone battery by mindlessly tapping the screen over...and over...and over again, then I cannot think of a better way for you to do that but with StuckPixel's The Button-- A Social Experiment. It's everything you'd want in a game--social features, leaderboards, etc.-- except without any of that annoying "gameplay" stuff.

For fans of college basketball, there's no better time of year than the NCAA men's basketball tournament. It's wall-to-wall hoops action, particularly during the tournament's opening round when 32 games are crammed into two days. All those bracket-busting Cinderellas, buzzer beaters, and memorable moments--it's really a wonderful thing for sports fans.

Each year, more and more new cars include built-in connection options for iPods, iPhones, and Bluetooth devices. But if you’re not yet in the market for a new car, you can still get such connectivity via an aftermarket upgrade. Sony’s MEX-BT5700U, a member of the company’s Xplod line of automobile head units, is a solid option that lets you connect both iPods and iPhones.

You just need the right apps to bring out the best in your photos.
