So you finally waited until your previous cell phone contract is over… so you finally decided to bit the bullet and take a leap… so you finally got an iPhone… now what? The beauty of iPhone is not just what you get out of the box, but the unlocked potential that it hosts. Here are few categories accessory to consider:

iPhone 3G Screen Protector or Stylus Pen – One of the features that makes iPhone standout among all the competitors is its unique touch screen interface. Since the touch screen is the only user interface, in the perfect world, one will wish for a strongly scratch-resistant screen. Unfortunately, after little usage, one will easily notice the smudges and oil residues from user’s finger and face. Since the screen is the first (and often times, the only) thing the user focuses on, a screen protector is also a logical choice. Keep the iPhone’s screen clean and shiny with an overlay screen protector.

Another popular alternative preferred is to use a stylus pen, instead. Most ex-PDA users are more accustom to using a pointing device for typing and menu navigation. Both screen protector and a stylus are great ways to reduce wear on the touch screen.

iPhone 3G Case – The iPhone is priced as an high-end mobile device, so it would be wise to invest in a protective case. Proper casing will help reducing the risk of scratching and hardware damage during daily usage. It is also a great way to express your individuality.

More Cases:

• iPhone 3G Crystal and Aluminum Cases

• iPhone 3G Leather Cases

• iPhone 3G Premium Skin Cases

• iPhone 3G Graphic Cases

• iPhone 3G Socks and Pouches

iPhone 3G Car Charger – Although the iPhone 3G comes with a Sync data cable and an USB wall charger adapter for recharging the battery, it would probably be a good idea to have a car charger on the vehicle. iPhone’s attractive 3G and GPS network capability will quickly drain the battery power within hours. In most cases, it would be useful to have a car charger handy while on the road or traveling.

Another handy accessory to have on the road is a car mount. Whether you use the iPhone as a MP3 player while driving or taking advantage of its GPS feature, a car kit can keep your iPhone secured and easy to access.

iPhone 3G Headsets/Headphones – While on the topic of driving, the new state law (California and Washington) requires motorist to use a hands-free device when using a cell phone while driving. A Bluetooth headset would be a great addition for those that like to talk during the traffic jam.

Audio enthusiast that uses iPhone as a MP3 player probably will not be satisfied with the default headset that came with the device. The standard 3.5-mm stereo headphone minijack makes it easy for users to find the headphone of their choice.

iPhone 3G External Battery – With all the exciting features the iPhone offers (audio playback, video playback, internet…) it is easy to get carried away and drain the battery faster than expected. If that is you, invest in an external battery and never revisit that scenario.

Thanks to the popularity of iPhone, there are tons of other add-on’s to consider (such as speakers, docks, cables, extended warranty, Apple’s Mobile me service…). Of course, the AppStore and iTune also offers limitless potentials to the application of the handset.
