Thanks to iOS 5.1 the relationship between Siri and Yelp just got a little bit closer. The iPhone 4S has used Yelp from the beginning to provide answers to all of your questions surrounding local businesses, especially restaurants and bars. The latest firmware update provides more interaction from the results that Siri pulls up from Yelp.

Now with the Yelp iPhone app installed, tapping a business listed in Siri's search results will bring you directly to the business in Yelp. This provides full access to all of the pertinent information you may need before heading over to that address, such as hours of operation, review details, and photos.

The ability to stream music from your iPhone directly to speakers or an AirPlay-enabled device like the Apple TV is one of the perks of iOS. Some music apps, like Pandora, include a handy AirPlay button that makes turning on streaming simple. So how do you get other music playing applications on the iPhone to use AirPlay?

Just because the app developer didn't include the AirPlay button directly in the app interface doesn't mean you're out of business. Apple has included a default AirPlay switch in iOS along with volume controls on the multitasking dock. Accessing AirPlay from any music app is possible as long as your AirPlay-compatible devices are properly configured on your Wi-Fi network.

Reports of Apple considering a larger display size on the next generation iPhone are nothing new, but according to a South Korean newspaper, suppliers have already taken orders for the components. Apple is said to be moving forward with a whopping 4.6-inch screen on the iPhone 5.

This would be a significant jump from Apple's iPhone-standard 3.5-inch Retina display. Competing smartphone manufacturers such as Samsung already offer models with 4.3 and 4.6 inch diagonal screens, while Apple has yet to bump up this dimension on the iPhone.
