On the Mac commercials they're so proud of the saying 'There's an app for that..'

Being an iPhone user and a gamer, I decided to put Apple to the test to find out if what they advertise is really true. I have an iPhone 3GS and I have to say, it's one of the best phones I've ever used. I use it for my email, Twitter, Facebook and a whole lot more.

However, I'm curious to see if it will enhance my gaming experience any. Let's take a look to see the five iPhone apps I found that every gamer should have.

IGN.com iPhone App:

Like many of you, I often turn to IGN for game reviews, previews, screenshots etc. With their iPhone App, you can take those features with you. There are even video reviews. You can sort by game genre or by platform, and the rating the reviewer gave it is on the right hand side. You can bookmark reviews and videos, which is handy so you don't have to go searching for it again the next time you want to see the review.

Inside XBox 360 iPhone App:

The only Microsoft endorsed mobile app for XBox Live, Inside XBox 360 comes packed with features. You first add your XBox Live Gamertag which then lets you stay connected with friends (you can see their online and offline status).

You're able to scroll through various XBox 360 stories, game info, community news brought to you by Major Nelson, and game teasers and game trailers. I was surprised by how feature packed this one was. A worthy addition to my iPhone.

Modern Warfare 2 Countdown iPhone App:

Okay, I think we're pushing it with this iPhone app, but still, it's worth it just by the title. Modern Warfare 2 is arguably the hottest anticipated title of the year, and if you have this app, you'll know down to the second when it's released.

So, there's my list, what are your favorite gaming iPhone apps?
