Everybody wants to be Jony Ive’s friend, so he probably gets invited to a lot of the dinners where Silicon Valley’s elite just hangout, scarf down pizza, and get blitzed on wine. We rarely see pictures of such events, but last night a picture was posted of Sir Jony himself hanging out with 11 of the most powerful people in Silicon Valley.

The dinner was hosted by Nirav Tolia – a longtime Silicon Valley entrepreneur – and featured the CEOs of Twitter, Yelp, Path, Dropbox, Yahoo, and other companies. What’d they do besides eat pizza? Did a wild night of karaoke follow over at Marrisa Mayer’s manor? Who knows? Who cares? But we’re glad Jony gets to hangout with people outside the mothership from time to time.

Here’s a list of everyone that was present at the dinner:

Kicking off this week’s must-have apps roundup is a stunning new weather app called Solar, which boasts a simple, intuitive user interface and a no frills approach that doesn’t suffocate you with information you’re not interested in. There’s also a great new drawing and animation app from Disney that you and your kids will love; a great new photography app that adds bokeh light effects to your photos; and updates to Google Earth and Yelp.

Yelp just delivered the latest version of its iOS app to the App Store, and the company promises it’s “literally filled to the brim with awesomeness.”

“We’re not joking — we had to get an intern to stand on the top of it just to get it zipped up and shipped to the App Store.”

In addition to brand new business pages, Yelp 6.0 delivers support for Yelpy Insights, the ability to like and compliment tips, and lots more.

Although iOS 6 looks a lot like iOS 5 on the surface, a number of Apple’s built-in apps and services have received some big changes. The biggest overhaul comes to the Maps app, which has done away with Google Maps in favor of Apple’s own 3D mapping service. Another feature you can look forward to in Maps, according to an Apple document sent out to developers, is Yelp check-ins.

Before Apple released its iOS 5.1 update to the public earlier this month, clicking on a Yelp link after performing a search with Siri did absolutely nothing. Now, however, it’ll take you straight to Yelp’s iOS app — or the App Store if you don’t already have it installed.

Still struggling to think of things to do this Valentine’s Day? Maybe you haven’t even got a date yet. But don’t worry, our app guide is here to help. We’ve compiled a list of great iOS apps that will make you the perfect valentine on February 14. They’ll help you find a date, book a table for dinner, buy movie tickets, and even send flowers. All you’ll need is your iPhone.

A new service from Piecable, called Piecable Viewer, allows you to run iOS applications in your web browser. They’re not just watered down demos either; they’re complete applications – just like you’d get from the App Store – that run on Flash with just one additional line of code.

The service provides developers with a great way of giving people access to their applications for testing, without having to worry about iTunes redemption codes or the UDID limit Apple places on developer accounts. All they have to do is sign up to the Piecable service and choose one of its tiered pricing plans, add an extra line of code to their application, and upload it to the service. They receive a link to the app on the web which can be sent out to agencies, clients, organizations, and the press, enabling the recipient to play around with the application in their web browser.
