Square is quickly becoming one of the most convenient and coolest ways for small businesses to process transactions. If you’ve ever visited a shop that uses Square you’ve probably seen a number of improvised iPad cash registers, but Square just debuted its own iPad register called Square Stand.

The Square Stand will go on sale starting June 8th for $299, but you can already pre-order it on Square’s website. The new hardware is to be utilized in conjunction with the Square Register app that is already used by thousands of businesses across the country.

Philips Hue lightbulbs have quickly become one of our favorite iPhone accessories for the home. Not only can change your lighting to fit any mood, you can also create light shows with your music, and now Philips is adding some new features to the bulbs to make them even more powerful.

Philips released a new update for its Philips Hue app for iOS today that adds a number of features including geo-fencing, timers, alarms, and IFTTT support.

Here’s a video of some of the new features:

At its BlackBerry Live event in Orlando, Florida, BlackBerry just announced that its popular BlackBerry Messenger service is going cross-platform. This summer, BBM will finally be available on Android and iOS — and it will be completely free.

Facebook for iOS has received another new update today, which adds a new “photo viewer button” which allows you to save and share images, and make them your profile picture. It also makes improvements to places editing, and more.

Twitterrific, one of my favorite Twitter clients on iOS, got a new update this week that adds Readability integration for bookmarking tweets you want to catch up with later, as well as support for image hosting service Droplr. The update also comes with a ton of bug fixes and improvements.

Heroes and Castles, Foursaken Media’s mix of a third-person shooter with the castle defense genre, is a heck of a lot of fun to play, and today the iOS game has gotten a big old update, with a ton of great stuff to extend the fun, possibly enticing new players to try it out as well.

There are three new characters to play and level up: a stealthy (and free) Assassin, a natural-magic Druid, and a brawny Barbarian character. You’ll be able to put each through their paces in a brand new single player campaign, available as an unlock upon completion of the original campaign, with an entirely new environment and a ton of new enemies to battle.

Have you ever had one of those Siri moments, where you ask her to search for something, and she interprets your speech incorrectly? I’m guessing all of us have, at one time or another.

One thing Siri doesn’t do very well is provide for “no I meant…” error correction, at least using speech. Next time you use Siri and the result is something you didn’t expect, don’t just press the home button in frustration, but correct Siri using your iPhone or iPad keyboard instead.

Killing iOS apps — not just closing them, but killing them completely — is nowhere near as simple as it should be.

First you have to double-tap the home button to open the multitasking tray, then you have to tap and hold the app’s icon, and then you have to close it by tapping the tiny circle. That’s a pain if you have several apps you wish to kill at once.

But with a new tweak for jailbroken iOS devices called Slide2Kill, you can completely kill iOS apps with just a swipe.

iTunes users spend an average of $40 a year on digital content, according to the latest report from Asymco’s Horace Dedio. And with more than 500 million users, Apple is raking in over $5.5 billion in iTunes sales revenue every single quarter.

That’s more than some technology companies see in total, and Apple’s making it on just one service.

For a long time, Steve Jobs and Bill Gates were two of the biggest competitors in the technology industry. They were both early pioneers of desktop computing, and their companies were battling each other for every ounce of market share they could get their hands on.

But those shared experiences eventually led to the two becoming good friends. In a new interview for CBS’ 60 Minutes, Gates fondly remembers his old foe, and emotionally recalls his last visit to Jobs’s Palo Alto home before he passed away in October 2011.
