The music mobile discovery provider Shazam has given an update to its application that brings back unlimited tagging for songs. Back in 2008 when Apple opened its doors to its first app store for the iPhone and iPod Touch, it was one of the most popular downloaded applications. The Shazam application was offered as a free download, and it had the ability to tag unlimited amount of songs that you wanted to listen to without any restrictions. That changed in 2009.

The Mac App Store is now available and ready for you to download. To get it, simply check for updates on your computer as it is part of Mac OS X v10.6.6. Once you reboot, it will appear in your dock. As you can imagine, it didn’t take me long to get this app on my computer. And I’ve already formed some opinions about it. At first glance, you’re going to realize that it looks a lot like the iTunes App Store (this is a no brainer), and, as you can imagine, it uses your same log-in and your gift cards are available for use here.

There are all sorts of interesting numbers to be pulled from Apple’s App Store and iPhone platform. However, when you take those numbers and lay them out in a way that is extremely appealing, it’s even better. That’s exactly what App of the Day’s most recent infographic (link below) does. For instance, I could tell you that 33% of all apps are free while only 1% of apps are more than $24.99. I could also tell you that 7,000 of the 50,000 book apps come from one developer.

Interested in knowing what apps are on the majority of iPhone owners phones? Also interested in seeing which developers have seen hundreds of thousands of downloads of their apps and see thousands more every day? Then be sure to check out Apple’s App Store Essentials Hall of Fame. Just in time for the beginning of the holiday season, this page highlights some of the most popular apps of all time. As you can expect, Angry Birds is the first app you’ll see.

One of the biggest complaints about the App Store thus far has been that users have no way of really trying an application before they spend the money on it. Apple has launched a section of their App Store entitled “Try Before You Buy,” but while this may seem like a way to demo applications, it technically isn’t. This part of the App Store simply links to applications that offer a “Lite” (free or ad-supported) version of the full paid version.

Or should that be Appy Birthday? Either way, the App Store turns two today, having gone live on July 10th, 2008. Oh, sure, we could go on and on about the importance of the App Store and how it revolutionized smart phones and made millionaires of college kids and what have you, but wouldn’t you rather use it than read about it? The folks at Appsgiving.com would agree, and they’ve got a friendly suggestion for you…

On July 1, Apple flicked the switch on their mobile advertising system, iAds. There’s already a collection of applications using iAds—including Air Hockey Gold, Tiptitude, Removem Free—with reports of some customers downloading applications simply to see iAds running. When was the last time you downloaded an application for its adverts? Typical Apple, eh?

Just over three months ago, Apple announced their App Store had reached two billion downloads of various applications created by third party developers. This month, Apple stated the App Store has now topped a staggering three billion downloads. This not only means that a billion applications were downloaded in a span of three months, but also that over three billion apps have been downloaded in just over 18 months since the store’s inception

CNBC is going to air “Planet of the Apps: A Handheld Revolution”—a one-hour documentary that aims to portray how the iPhone have changed lives, while showing insights into the many developers behind the apps. While the majority of the documentary will focus on the Apple iPhone App Store, CNBC’s Scott Wapner will also take a look at Apple’s biggest competitors, namely a Verizon and Google Android deal.

When iPhone OS 3.0 was first released, Apple stated that only paid apps would be able to take advantage of in-app purchases. This allowed developers to offer, say, the first 10 levels of a game, then to charge a little extra for additional levels. Now, free applications will be able to offer upgrades via in-app purchases, which will hopefully clear the App Store of the hundreds of lite titles of which I am personally not a fan.
