When Facebook introduced us to Facebook Places last week, it rolled out a new version of the iPhone app to bring the new feature to many of its mobile users.

While Places took center stage, a number of smaller features and tweaks were added to the latest iPhone app, not the least of which is the ability to play with your privacy settings on a post-by-post basis.

Mobile media company ParkVu is today introducing a new Facebook application called Music WithMe which publishes your iTunes music library to Facebook where the tracks it contains can be shared, liked, commented on and discussed among your friends.

The app, which also requires a desktop software download (currently Windows-only, Mac coming soon), connects your iTunes music library to Facebook and then continually syncs changes as you purchase and add new music.

Social search company Wowd has introduced a new tool for advanced Facebook search, and it's a desktop app. Actually, it's a desktop app that runs in your browser..but more on that later.

What Wowd promises is a tool to "filter Facebook." It lets you create custom feeds, read personalized summaries, remove game spam from your News Feed and search your social network with advanced tools.

But will Wowd "wow" you?

Facebook now has a so-called "panic button" available on its site that allows users to report cyberbullying, hacking attempts, harmful content, unwanted sexual advances and other forms of abuse to the U.K.'s Child Exploitation and Online Protection Centre (CEOP), the organization behind the button's launch.

According to the BBC news, the launch is a victory that came about after months of negotiation between CEOP and the social networking site. Says Jim Gamble, CEOP's chief executive: "Today... is a good day for child protection."

Facebook is launching a new security measure that is clearly a response to the recent threats caused by numerous rogue applications that have spread virally across the social network. According to news from the Facebook Developers blog, all application developers must now verify their Facebook account by either confirming a mobile phone number or adding a credit card to their account.

The new procedure aims to cut down on the number of rogue applications created by hackers and spammers by forcing developers to share personally identifiable information. Unfortunately, say multiple security researchers, verification alone is not enough to stop these malicious apps.

The Facebook OpenGraph Search API is experiencing an outage that began last night somewhere between 7 PM EST and 8 PM EST, as best we can tell. After receiving a tip from a Facebook developer who noticed that his social search engine built on top of the Facebook platform, Booshaka, stopped updating with fresh content, we began investigating. This morning, we performed several searches against the API including queries for popular words like "graduation," and found that although the results displayed show a recent "updated" timestamp, the "created" timestamp is now pushing 15 hours old. Surely, someone on Facebook has mentioned "graduation" in a Facebook update after 7:18 PM EST last night?

A new application aims to put users back in control of their private data stored on the increasingly public social networking site, Facebook. With "The Green Safe" app, Facebook users can now export their profile data for offsite storage on Green Safe's servers. Data can then be purged from Facebook itself, allowing only friends to view profile information by way of a profile page tab labeled "My Info."

The tech world is still reeling from the impact of Facebook's radical changes, announced last week a the F8 developer's conference, and their implications for privacy, the open Web and the future of social networking. However, these newly introduced features, such as the "like" button for websites, social plugins and Facebook's Open Graph API, have spurred some early-adopting developers to create tools for end users that include everything from bookmarklets to search engines. Over the course of the past week or so, a number of these tools have been covered by leading tech blogs (including us, of course), but we wanted to create a resource that lists all of them in one place.

The knee-jerk reaction has begun. Friend after friend after friend is posting the same chain-letter-like status update with simple directions on how to opt out from Facebook's new sharing capabilities.

It's spreading like wildfire, but we have to ask - has anyone considered the up side to any of these changes?

At Facebook's f8 conference, founder and CEO Mark Zuckerberg announced that the company was removing restrictions on user data retention within Facebook applications. Previously, the company had a policy where developers couldn't "store and cache any data for more than 24 hours," Zuckerberg said while speaking to the audience of Facebook developers crowded into the San Francisco Design Center on Wednesday. "We're going to go ahead and...get rid of that policy," he said. The audience cheered.

But should Facebook end users cheer this news, too?
