Apple announced the much-anticipated iOS7 today during WWDC's keynote address, and it did not disappoint. Among the many improvements and new features, one area that Apple has come a long way in addressing is Security. From keeping our logins and accounts secure, to helping to stave off iPhone theft, security is clearly a priority for Apple. The new iOS features Activation Lock, iCloud Keychain and a new AirDrop, so let's dig into each.

Activation Lock

Find My iPhone has been an integrated part of iOS and both iPhones and iPads for a while now, and has helped thwart countless would-be thieves, enabling the return of stolen devices to their rightful owners.

LinkedIn released an update for their mobile apps today that is, in a word, gorgeous. The entire app has been rebuilt and revamped to the point that, I'm suprised we didn't have to delete the old app and download an entirely new one. According to the LinkedIn Blog, the update is designed to "make it easier for our members to quickly discover and engage with the rich professional insights being shared across LinkedIn to help them make smarter decisions from wherever they may be working. We’ve designed the new LinkedIn mobile phone app for every professional, with a richer and more engaging stream and more personalization features."

Twitter announced today that they have refreshed their app for Android, which gives a much more native Android look and feel. It features:

• "wider and taller timelines that fill the screen"
• flat navigation bar
• tap and hold for quick actions
• navigate between tabs by swiping across the screen
• auto-suggest usernames and hashtags in search

Additionally, iOS apps and the mobile web version have all been updated to display more content and information in expanded tweets, namely: photo galleries, apps and product listings.

Facebook has released a new version of their iPhone app today that features an all-new button design, as well as free calling to anyone in the U.S. or Canada integrated right into the main app.

According to the update:

New button design makes it easy to like, comment and share posts in News Feed.

• Improved buttons to like, comment, and share posts
• Share button to re-post stories from your News Feed now available in all languages
• Call friends for free right from Facebook (US and Canada)

Be sure to note that when calling someone, you will be using your data plan, so take note of your allotment if you're not on WiFi.

This is version 5.5 for the Facebook App.

Businesses that want to be successful with social media and blogging must be mindful of news topics and trends within their industry. Your social media activity should be packed, up to 80%, with content and information from other sources, reserving just 20% for talking about yourself. At the same time, breaking news and important industry stories are ripe for great blog posts (we call this newsjacking). In order to monitor potential sources of information for sharing or blogging, business owners need to invest some time into a few tools.

Twitter announced today a major improvement to their Search and Discovery features, and these improvements are immediately accessible through the mobile website as well as iOS and Android systems. According to the update, version 5.3 includes:

Instantly access great content with improvements to search and Discover.

For local small businesses, one of the keys to search engine marketing is making sure that if a customer is searching for your business, they can find it easily. This means making sure that your business has a regional listing in each of the major search engine's local directory, like Google+ Local or Bing Local. Customers are also using apps and social networks like Foursquare and Yelp to find, rate and review local businesses.

The udpate includes Google+ Community support, profile editing, a brand new stream design and more. There are updates for both Android and iOS users, and some of the features are a little different depending on the platform.
