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.

You can buy it from the App Store here.

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.

You can buy it from the App Store here.

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.

You can buy it from the App Store here.

The time is upon us ladies, gents and iPhone hopefuls - the videos for the Insanely Great Tees iPhone Contest are in, and now it's time for us all to chose a winner from the finalists. Embedded in this post at Insanely Great News are ten YouTube videos created by the chosen finalists. Towards the bottom of the post is an area where you can vote for The One Video to Rule Them All, as well as six honorable mentions.

Personally? I think Garbled Text Messages takes the cake for its excellence in production and execution. I'm a little bothered that most of the videos focused on just one specific feature or advantage of the iPhone instead of advertising a little more broadly, but it ultimately looks like everyone had fun which is what matters most.

Insanely Great Tees, who we've mentioned before and dearly love here at TUAW, has announced two new shipping shirts from that batch we all voted on. The "I'm a Mac" and "Binary Tree" (both $17) are ready to ship and keep you clothed, just in time for Macworld 07! I was personally hoping for the "cmd + s the whales" and "Vector G" shirts as well, but hey, I'll take what I can get.

Insanely Great Tees, the clever new Mac-centric shirt shop, has announced 6 new t-shirts - but not all of them are going to see the light of day. Apparently the insanely great crew are having a tough time deciding which ones they like most, so they've put it to a vote for the rest of us. Head over to Insanely Great News (their blog) to see all shirts laid out, each with their own voting options ranging from "I'd wear it!" to "Eh..." and even "It's the worst."

If you have a minute, head over and get to voting. I'm in the market for some new threads and I'd wear almost every one of these (sans the Camera Icons shirt), especially since there aren't nearly enough shirts about type in the world.

The internet is lacking in one thing: purveyors of geeky t-shirts. Luckily, Insanely Great Tees has just launched, and they are selling a few Mac related t-shirts for the Mac Geek in your life. Pictured to the right is 'The Bomb' shirt, a sight which will be familiar to long time Mac users.

Also amongst the collection are Heart and Magic Eraser, featuring everyone's favorite Undo command.

All the shirts cost $17 and are available in small to extra large.
