Once again, without fail, here are some of the best iPhone apps that you can find in the App Store this week:

SkiFree

Ahh, what fond memories some have while playing this game during their computer classes back in third grade.  If, like many others, you have been playing computer games since the early nineties, then you probably know this addictive game.  SkiFree is a simple, yet fun and addictive skiing game where you ski down an endless slope, avoiding obstacles like trees, other skiers, boulders, and the "rare" abominable snowman.  You can also jump on small ramps to gain points along the way.  Its simple graphics and gameplay make it a great game for passing time or for a good laugh.  While this iPhone version of SkiFree doesn't have the snow monster yet, it's still loads of fun and you can download it now for free.  Who knows, perhaps in future updates, you'll see that fuzzy, abominable snowman that you've been missing for all of these years.

PayPal

If you have ever shopped online or made any type of monetary transfer through the Internet, then you are probably well aware of PayPal.  PayPal is an online service that allows you to send and receive money to individuals and businesses.  It's a fast and easy way to make monetary transfers.  The PayPal app makes it easier than ever to make money transfers through the Internet.  With this app, you can check your balance, request money, withdraw funds, and more.  Not only do you gain access to all of the regular features and services of PayPal, but this app also has the "Bump" feature, which allows you to pass contacts and start transactions just by "bumping" your iPhones together.  Grab it now for free.

Etude

For the iPhone-owning musician or simply anyone who loves music, Etune is a great app that can prove extremely helpful.  The main function of Etude is to be used as a sort of electronic sheet music.  Beyond being a mere digital interface for sheet music, Etude allows you to find and choose from hundreds of songs.  The song will then appear on your iPhone in sheet music form.  Then, the keyboard interface below the sheet music shows you exactly how the notes in the song should be played.  It's easy to use and extremely useful for anyone who is musically inclined or anyone who is inclined to learn music.  There are also a bunch of customizable settings so you can get Etude working exactly how you want it to.  You can even share the music you're trying to learn with social networking sites such as Twitter and Facebook. The database of songs is ever-growing so get on board now.
