If you look under your seats, you'll find a bevy of free iPhone apps. That's right ... you get an app, you get an app, everybody gets an app (or 16)!

We've mentioned Chilli X a few times, and I've developed a fondness for their collection of sleek, simple iPhone apps with great-looking interfaces. And now it's their first birthday, and they're giving out presents: this weekend only (starting right now), you can grab any (or all) of Chilli X's iPhone apps for FREE.

There are plenty to choose from; 16 apps in the App Store and one just submitted for approval today. We've mentioned Done [iTunes link], MyCal [iTunes link] and Playlist Alarm Clock [iTunes link], but much has happened since then. What follows is a roundup of some of the latest apps, but you can find them all by searching for "Chilli X" in the App Store.

With just a few months to go before launching the Windows Marketplace for mobile applications, Microsoft has published details on porting iPhone apps to its Windows Mobile platform. It's a case study of the app Amplitude [App Store link], which lets users hear far-off sounds with ease. It's a detailed writeup that takes readers through the entire process.

Microsoft will have quite a task ahead of them in this market, considering Apple's considerable lead and foothold. However, there are many (to say the least) Windows Mobile devices out there as well as people for whom "Windows Mobile" means business.

It will be interesting to see if and how iPhone/iPod touch app developers choose to move their products to Windows Mobile. The Windows Marketplace for mobile applications is expected to drop between September and December of this year, as are Snow Leopard and Windows 7. It's going to be an exciting autumn.

Last week we were pretty excited that the new Slingplayer app for iPhone had been submitted to Apple for approval. Now it seems, the folks at SlingMedia are determined to really get a large percentage of their customers angry about forcing them to have the latest Slingbox hardware in order to be compatible with the iPhone/ iPod touch app.

A page on the SlingMedia website suggests owners of older Sling hardware get an upgrade because the new iPhone software "and future services yet to be announced will only be supported for customers using Slingbox SOLO, Slingbox PRO and Slingbox PRO-HD products or forthcoming SlingLoaded products." That still leaves a lot of the older hardware a no-go, and that older hardware worked well with the SlingPlayer Mobile app on other cellphones, including those running on Windows Mobile, Blackberry, Palm and the Symbian OS.

Our sister site, Engadget, reports that they've been told that previous builds of the app worked just fine with the older hardware, so this may just be runaway greed and avarice at SlingMedia.

In my post last week I said that Sling users would be circling Apple HQ with torches and pitchforks if Apple did not approve the SlingPlayer Mobile iPhone app. Now those people might want to gather in Foster City, California to let the execs at Sling know that they don't want to be forced into an upgrade that is likely not needed.

Our thanks to various readers who sent this in.

The App Store might be only a few days old, but it has already proven itself to be a viable and potentially lucrative outlet for developers. With so many apps (and more being added all the time) for sale, getting exposure is extremely important if a developer wants to stand out in the crowd. Unsurprisingly, the market, especially in the games sector, is very competitive. But is the quest to compete leading to some unfair, and ultimately consumer unfriendly practices? Note: All of this data refers to the U.S. App Store, I'm unsure of the situation in other parts of the world.

We got a tip from an iPhone developer, who requested anonymity, about some shady techniques being employed by some developers to obtain a higher app ranking in the App Store. As it stands right now, if you choose to browse the App Store in iTunes, not using the search but using the "All iPhone Applications" category, apps are visually displayed in alphabetical order. Well, they are supposed to be displayed in alphabetical order. As it stands right now, only five of the 21 titles displayed on the first page actually fit that criteria -- and they are the last five apps on that page.

Some developers have figured out that adding a symbol or space before the game name will promote the app to the first page. Thus, Solitaire City, which alphabetically should be on page 26, is the very first app listed in the store. Other tiles like Whack the Groundhog, $0.99 Sudoku and 'ColorRise 3D' are all listed on the first page, instead of where they should be cataloged.

Magnetism Studios, the guys behind Insanely Great Tees, have just launched four iPhone apps, which they are dubbing "Magnet Apps."

Two of the apps are $4.99 and two are $2.99.

Here are the details:

Tile Sudoku ($4.99)

Sudoku is a popular puzzle game choice for iPhone devs, but Tile Sudoku has a neat little twist. Instead of selecting a number from a list, you drag numbered tiles to the correct space on the Sudoku grid. If you make a mistake, you can move the tile to the correct space or back to the tile bar. I haven't used any of the Sudoku iPhone apps yet (I have played some of the web-based versions), but this seems to make a lot of ergonomic sense.

You can buy it from the App Store here.

Mr. Shuffle ($2.99)

It's Mr. Potato Head on the iPhone! Mr. Shuffle lets you create funny faces out of cartoon parts. You can then add speech bubbles or captions to customize the images further. While all that is cool, the most fun part is probably the feature that lets you add elements to pictures you take of your friends from the iPhone camera.

City Transit ($2.99)

Everytime I visit New York City, I dread having to carry around a transit map guide like a tourist. And even then, you never really know where the closest station is to your location or if there has been some sort of service change. City Transit aims to change all that. For $2.99, you get officially licensed MTA subway maps, a GPS-based station finder to find the nearest station (and it is integrated with Maps so you can get walking directions too) and service advisories from the MTA website, so that you know can quickly out about any line changes.

Magnetism has designed City Transit to have an expandable architecture and in the future you should be able to download maps for buses and commuter rail lines. This really looks like the perfect app for anyone who commutes to NYC.

File Magnet ($4.99)

File Magnet, which right now will only work in conjunction with Macs running Leopard, is a way to transfer files to and from your Mac from your iPhone or iPod Touch over Wi-Fi and then view them. It supports PDF, DOC, TXT, RTF, RTFD, HTML, PNG, TIF, JPEG. GIF and iPhone compatible movies and audio files. Support for Excel and iWork files is coming soon. So instead of having to e-mail yourself PDF files, you can just load the File Magnet Uploader on your Mac and send it directly to your iPhone.

It does require Wi-Fi to transfer files back and forth, and is not compatible with Windows.

All sorts of interesting iPhone apps have sprouted up these past few weeks, but unless you're checking out our own Erica Sadun's excellent work with iPhone apps, they can sometimes be hard to find or install. While Apple wants us to keep twiddling our thumbs in anticipation for true apps to come to the iPhone (perhaps they are just waiting for Leopard), a new Installer.app (of course, a beta) could help simplify things by acting as an iPhone app management hub. Installer.app can install and update a good handful of iPhone apps (with more to come, I'm sure) over Wi-Fi, and uninstall them as well.

Of course, you'll need to use iFuntastic command line tools like iPHUC or something similar to get Installer.app onto your phone in the first place, but after that it seems like this is a good solution for endowing your iPhone with new apps until Apple opens things up.

Media Temple, a well known hosting provider, has recently rolled out a beta version of their control panel made just for the iPhone. Judging from the number of folks who sent this to us (thanks to all of you!) there seems to be a large, and until now, untapped market of people who want to be able to register a domain from anywhere.

Aside from registering domains you can also restart services, pay your bill, add email addresses, and submit a tech support ticket. I'm not a Media Temple customer myself, nor do I own an iPhone (and we all know how I feel about iPhone specific web apps) but I must admit this looks slick. You can access the iPhone version of Media Temple's control panel here.

The 3rd Party iPhone applications are starting to roll in. Here's TUAW's list of currently available packages. I'll update this list as more apps become available and we hear back from more developers.

Hello World. Hello World Demo

KBDemo. Proof of concept Keyboard demo. Part of the larger Mobile Terminal for iPhone project.

Do Shell. Runs shell script embedded in App. Can be customized by end user.

iDecor. App version of the javascriptlet we posted about here. Sets your iPhone wallpaper based off an image left up on Safari.

TextViewDemo. Allen aka Pin's excellent UITextView sample.
