If you've been following along with all the World Cup live streaming action, it's very likely that you've noticed the annoying horns that are trumpeted during each match. You know, the ones that sound like an angry swarm of bees? Yeah, that's the one. Called a Vuvuzela, these horns are used by soccer fans all over the world to show support of their teams. Although the horns have met with many complaints since their first appearance in the 1970s that shouldn't stop you from downloading the free Vuvuzuela 2010 app that puts you and your World Cup party guests right in the middle of the stadium. Well, it will sound like it anyway.

The app is simple — just touch the horn, or shake your iPhone or iPod Touch to create the signature sound. The good news? This app won't blast your eardrums nearly as much as the real things do! Add this app to your list of must-have World Cup gadgets and party on.

With all the iPhone 4 preorder madness, you may have missed a few other updates coming from Apple yesterday — a new Mac Mini refresh and the Apple Store App for iPhone.

First up, the Mac Mini: an all-new 7.7-inch unibody aluminum casing packs in an HDMI port for hi-def viewing, SD card slot to transfer photos, an upgraded NVIDIA GeForce 320M graphics card, 2.4 GHz Intel Core 2 Duo processor, 320GB hard and 2GB of RAM. Additionally, there's now an integrated power supply (which frees up some room from that old power brick) and a removable bottom so you can upgrade your RAM yourself. Available now, prices start at $699.

Today in Cupertino, CA, Steve Jobs announced iPhone OS 4.0, which will be released to developers today and ship this Summer. Highlights include the expected ability to multitask, customizable wallpaper, folders, and more. The new OS will run on the iPhone 3GS and second-generation iPod Touch; older models will see some of the functionality, but key features — like multitasking — won't work on the 3G or original iPhone. Here's a quick roundup of some of iPhone 4.0's notable features:

• Multitasking: As Apple announced this feature, it acknowledged it was a long time coming — but chose to hold off on the functionality until now so it could be implemented without draining the battery or slowing the phone. When running multiple apps, double-click the home button to display a dock of apps currently in use; touch an app to switch between them. Yes, this means you'll be able to listen to Pandora (or any other streaming app) while doing other things. In fact, Pandora's founder was on hand and explained that you'll not only be able to continuously run the music service while using other apps, but you'll also be able to control it while your phone is locked. You'll also be able to switch between apps quickly and pick up where you left off instead of relaunching the app entirely.

This iPhone stand completely cracks me up — but it's amazing and completely creative. From a seller in the handmade marketplace Etsy (where else?) comes the iSpoon ($30), a stand for your iPhone or iPod Touch made from kitchen utensils. The stand, which comes in both portrait and landscape variations, allows you full access to the device's screen while propping it up in an easy-to-view fashion.

An obvious location for this fun accessory is in the kitchen for easy access to recipes and other cooking info, but it would look equally adorable propping up your phone on a bedside table, and both designs will work with the charging cable connected to your device.

We talk a lot about Craigslist here, and how easy it is to check sales on your mobile phone, but now, eBay is taking it to the streets with its new iPhone apps, which make buying and selling on the go pretty darn effortless.

First up is the eBay Selling App (free), which allows you to post an item for sale (while using your iPhone's camera to post photos), research similar items and prices, share your listings on Facebook and Twitter, and check the status once it's up. The eBay Classifieds App (free) lets you search locally, as well as post your own items for sale without all the hassle of bidding, and upload up to eight photos from your iPhone camera or library. Combine those with the power of the new PayPal app, and, well, you may never need your computer again — your whole eBay business can be done from your phone! Just make sure to check out my tips on taking great resale photos and some apps that will help you make the most of the pics!

Besides producing pretty protective cases for the new iPad, iLuv also makes great accessories for other Apple products. The latest iPhone/iPod Touch dock from iLuv is no exception, and serves as more than just a speaker. The iMM190 Stereo Speaker ($90) features a unique shape, allowing it to display your iPhone horizontally or vertically for optimum photo and video viewing.

In addition to enhancing video from your phone, it also doubles as an alarm clock. Download the free iLuv App Clock from the iTunes App Store; the straightforward app displays the time (either vertically or horizontally) and features changeable color themes. The time is displayed in a large, easy-to-read font, and also displays current weather conditions for your location at the top of the screen.

Apple just made a new upgrade to iTunes yesterday, allowing you to gift an app the same way you can with audio and video. Apps make a great gift, especially if you know someone who incessantly uses their iPhone's camera — gift them a nice little camera pack — or has a bad habit of texting while driving (tisk, tisk — use ShoutOut instead).

Now that all of your friends have phones with cameras attached, there's probably a ton of links to photos posted in your Twitter streams. Now, there's a new iPhone app that makes viewing all of these photos super simple, without having to click on any links. PhotoNest for iPhone, available for $2 in the App Store, makes it easy to view your friends' photos. Instead of having to visit a site like TwitPic or Yfrog to view photos, use PhotoNet to scroll through them on your iPhone just as you would scroll through any photo album. Plus, you can use the app to take photos and post them directly to your own Twitter stream. If you're viewing friends' photos, simply shake your phone to refresh the photo stream.
