Back in the late 1970s in Chicago, Bell System built the first mobile phone system that could support hundreds of concurrent connections. That was a big deal compared to, for instance, New York where only a dozen or so people could use the cell network at a time. When this video was made in 1979, Bell had 1,300 customers using its mobile network, and, if you believe them, their calls were clear and the connections never, ever dropped. Maybe they don't make them like they used to.

When you see as many apps as we do at RWW, you begin to feel like it's all been done. So many of the everyday jobs for apps to do can already be done by at least one app (if not dozens). How many ways can you share photos with your friends? How many social networks and check-ins and restaurant-discovery services do we need?

Lately, we've started to see a new class of app emerge just for managing these tasks across their various apps. The idea of apps for our apps sounds ridiculous, but some of them are neat, and some are downright lifesavers. Here's a round-up of apps you should use if you want to bring your many social networks into one dedicated place.

Microsoft paid Nokia $250 million in the fourth quarter to adopt the Windows Phone operating system, according to Nokia's fourth-quarter earnings report released Thursday.

That was the first in a series of so-called "platform support" payments believed to eventually total billions of dollars. To date, Microsoft and Nokia have been quiet about the deal's specifics, perhaps because it appears as if Microsoft is paying Nokia significantly less than its paying other cellphone manufacturers.

Go ahead and check those work emails on your smartphone: a new study says it's time spent checking Facebook and other "personal" social networks that is stressing you out.

It gets worse: the more times you check your smartphone, the higher your stress levels. The study also suggested people who are used to getting lots of text messages and push notifications on their phones will feel stress levels rise if they hit a stretch where their phones are silent. In the worst cases, study subjects experienced "phantom" vibrations when, in fact, they had not received an alert.

That the Web has revolutionized music is not exactly a news flash, but most people typically think about that in terms of music consumption. iTunes. YouTube. SoundCloud. Spotify. Group listening sites like Turntable.fm. Recommendation engines like those of Pandora, Last.fm and the Echo Nest. Now voice-controlled Internet radio apps are coming pre-installed in new cars. There's no doubt that they way people discover and listen to music has changed radically, and will continue to do so.

The Internet and mobile technology are beginning to have an equally significant impact on the creation of music itself. Extremely powerful recording, DJing and sequencing software is making its way from laptops to tablets and smartphones, for example. Now, the way people learn to play music in the first place is changing as well.

Path 2.0 is the first newfangled social app I've been able to get my friends to use since Facebook complacency set in. I had my reservations at first, when I was worried that Path would turn out to be nothing more than a pretty mirror for gazing at oneself. For a while, it was pretty lonely in there, but after using Path to document my week on jury duty, I knew the app could offer something meaningful.

As it turned out, the Path experience wasn't only compelling to me because I'm a professional nerd. Over the holidays, I showed Path to a bunch of my best friends, and they all fell in love with it. Now that I have close people there, Path has become important to me. It's on my home screen, and Facebook is not. Path is not on the Web; it's a place in itself, and that's why it matters.

Friday night, New-Year's-Eve Eve, I had just stepped away from my blogging station when Yobongo CEO Caleb Elston recommended I open the app. That's interesting, I thought to myself. I never had to download an update. I've been watching Yobongo since it launched. It has only been open in Austin, New York and San Francisco since its debut, but I've kept my version updated, anyway. When it launched in my area, I didn't want to miss it.

So when I opened Yobongo on Friday, my first thought was, There must be a Web app in here somewhere. My second thought was, Oh, wow! Global Yobongo chat and private rooms are open to everyone! So that's the news. You can now use Yobongo no matter where you are, although the location-specific rooms are still only in select cities. But there's more. As Caleb told me coyly, "iPhone is just the start" for Yobongo. "We want to help people communicate more efficiently," Elston says, and that means everybody.

You're more likely to use your smart phone to search for information about sexually transmitted diseases and mental health issues, but searches on serious conditions like diabetes and cancer are still coming from desktop and laptop computers.

Those were among the findings in a study released by Healthline Networks for the top searches on its health information site in 2011. Chlamydia was the number one query for mobile device users, while cancer was the top search from desktops and laptops.

Google+ just announced that feature phone users can now create a Google account. Googler Mohamed Fouad describes this as an effort to enable the hundreds of millions of people with feature phones but no computer access to create an account.

By visiting plus.google.com from a feature phone browser, users can now create a Gmail and Google+ account. This month, Google has extended features of the Web versions of Gmail and Google+ to allow free voice calls to any phone number. Building features for basic mobile phones helps Google extend its reach to a huge, untapped market for Web services.

WordPress has released version 2.0 of its Android app for mobile blogging, and as a WordPress for iOS user, I am jealous. The new app launches with a screen that covers just about every first action a mobile blogger needs. It's arranged in correct order of priority, and it uses a big, easily tappable grid of buttons with an "action bar" over the top to handle the rest.

Other additions are catching up with WordPress for iOS, but they're welcome. The post editor now has a formatting toolbar above the keyboard, and the app now has a tablet view. The app also adds post uploading in the background and gets a few other fixes. This is an open-source app, and it's the best mobile blogging interface I've seen yet. What's up with everybody else?
