With only about an hour and 20 minutes left of 2010, I figured I’d write a post about my favorite iPhone and iPod Touch applications that I have used or heard about in 2010.

While not all of these applications came out in 2010, I still think they are worth mentioning, so here are my favorite iPhone applications of 2010: (in no particular order)

1. FaceBook

The FaceBook application for the iPhone, iPod Touch, and iPad has made it easier to see what my friends and family are up to, as well as keep in touch with them on the go. Also, the FaceBook mobile application has made it easier to share photos on the go, as there is no need to upload any pictures to a computer first, as they can be uploaded on the fly.

2. Twitter

The Twitter application is on my list because it makes it easier to view and create Twitter status messages on the go. In addition, the application makes it easy to search for and follow other Twitter users, without having to go on a computer to do so. The Twitter mobile application, formally Tweetie, which used to cost $2.99, was acquired by Twitter in April of 2010 and released for free soon after.

3. FourSquare

FourSquare is a geolocation application that enables users to see the different places and venues that people, such as friends, family, and co-workers are checking into. Each time a user checks into a location, they are awarded a certain number of points. Also, users can earn different badges by doing and accomplishing different things, such as checking into 25 different venues.

The FourSquare user who checks in at a certain location the most is called the “mayor” of the location and in some instances, the mayor of a location can be offered deals by the venue. While not many of my friends and family use FourSquare, I still find it interesting to see where they are checking into, as well as fun to check in myself.

4. Shazam

Shazam is on the list because I find it to be really useful when you’re trying to find out the name of a song or perhaps the artist who created it. All you need to do is take out your phone, launch Shazam, and press the “Shazam” button, and the application listens to the song, sends the information, and then returns the name of the song, artist, as well as other information. There is also an option to purchase the song from iTunes, which is nice if you enjoy a particular song. All of the songs that you “tag” are available in a list, as well, which is also a nice feature.

There is a free version of Shazam, as well as two paid versions, Shazam Encore and (Shazam)RED, which donates money to help fight AIDS in Africa. Both Shazam Encore and (Shazam)RED can be downloaded for $4.99.

5. Instagram

Instagram is a relatively new service, which enables users to share photos that they have taken with or have on their iPhone or iPod Touch. However, unlike other photosharing applications, Instagram allows users to apply filters to their photos, changing the way they look. Like other social networking applications, users can follow each other, as well as comment and like the photos that their friends, family members, and co-workers have taken. People can also geotag their photos, as well as post links to them on websites, such as Twitter and FaceBook.

6. DailyBooth

The recently updated DailyBooth application makes it easy to view and post pictures to the DailyBooth website, which is a social networking website that enables users to post pictures of themselves. The second version of the DailyBooth iPhone application also allows users to comment on and like people’s photos, as well as view users’ profiles, in addition to other features.

6. Plants vs. Zombies

Plants vs. Zombies is a tower-defense style game where users have to place various plants around a backyard, in order to prevent a variety of different zombies from getting to a house.

However, zombies are able to eat the plants that are placed, so users have to be careful to prevent the zombies from getting to their house. As the levels progress, more plants become available for use, but more and different types of zombies also show up, so users have to keep on their toes to defeat the zombies and protect their house!

7. geoDefense

geoDefense is another tower-defense game, where users have to prevent a variety of different "creeps”, or creatures, from getting to the end of a specific track. In order to do this, users are provided with different types of towers, such as blasters and lasers, which damage and destroy the “creeps” that are trying to get through. Like Plants vs. Zombies, as the levels progress, the “creeps” get more and more difficult to defeat, so it creates a fun challenge to create a good defense.

8. The Sims 3

The Sims 3 is a fun game in the Sims series, in which you have to control a character that you create, performing everyday functions, such as cooking, going to work, and even going to the bathroom. Characters are able to obtain jobs, as well as play mini-games, some of which award money, which can be used to purchase new items and upgrades for the character’s house.

9. Tetris

The Tetris application, by EA, enables users to play the classic game of Tetris on their iPhones and iPod Touches. Users can move the tiles and blocks around, as well as rotate them and more, simply by tapping, dragging, and swiping their iPhone or iPod Touch’s screen. There are also two different game modes that users can play, which are “Marathon” and “Magic”. “Marathon” mode enables users to play a familiar game of Tetris and “Magic” mode adds some new things, such as power-ups, the ability to draw your own brick, as well as other things, to the game.

10. Camera+

Camera+ is a camera application, similar to the iPhone’s native camera application, but with some additional features, such as a grid to line up your photos, image stabilization, burst mode, and the ability to edit your photos. Once you’re done taking and editing your photos, you can upload them to a website, such as Twitter or FaceBook, or export them to your iPhone’s camera roll.
