The iPhone is just about one of the most revolutionary mobile phones that have ever hit the market. The concept of the iPhone has long been introduced to the public, and the public, in turn, have been waiting eagerly for its release. Upon its release, the iPhone immediately garnered praises and reviews from both sides of the fence. But the many iPhone applications that come with the phone have indeed caught the attention of a lot of people from all over the world.

With the many iPhone applications available, you just might wonder if all of these are indeed needed. This would actually depend on your own needs because you would deem an application necessary only if it suits your needs, right? But all of you just might agree that the following iPhone applications are quite necessary as they come. In fact, you can go on saying that these are the applications that your iPhone just cannot do without.

iPhoneDigg

You surely must be familiar with Digg right now. But for the benefit of those who are not familiar with Digg, it is actually a website that contains articles topics revolving around science, technology, entertainment, and politics. Blogging, syndication, and social bookmarking are rampantly done on the website. Now, you no longer have to log on to the Internet, just to check the website out. With iPhoneDigg, you can now use your phone to browse through the top articles in any particular category you are interested in! The dig count, which influences the ranking of a particular article, is also listed alongside the title of the article, so viewing them is easily done. What’s more, iPhoneDigg comes in such a user-friendly interface that you won’t have any trouble viewing them at all.

JiveTalk

Now, this is indeed one awesome feature that your iPhone just cannot be without. This is actually an application that grants you unrestricted and unlimited access to virtually all Instant Messaging networks!

Google Reader

This canny application from David Cann is indeed a fantastic addition on the iPhone.

Gas.app

If you are constantly on the lookout for the rise and fall of gas prices, especially in your local area, then the Gas.app is indeed something you cannot be without.

Mind you, these gas prices are the current ones as well! All you have to do is input your zip code, and you can then leave everything to Gas.app! Do not fret if you are not all too familiar with the gas station the application suggests because the iPhone comes with Google Maps application as well. This way, you can easily find the gas station in question.
