This is probably the fastest iPhone ever created by Apple and users will instantly notice its speed once they launch applications on their new handsets. Web browsing is a breeze as pages are rendered in just a fraction of time. Email attachments can easily be viewed in no time at all. Enhanced 3D graphics enables a crispier display while improved performance lets users run applications without any glitch – a potent combination especially when playing game applications. According to Apple, the new iPhone is twice as fast as its predecessor, the iPhone 3G, and is more responsive.

Another feature that was enhanced was the camera. While the 3-megapixel camera is a bit on the low-end compared to some Samsung and Sony Ericsson handsets, it is still a welcome change from the previous iPhones. It takes good still photos and is replete with built-in autofocus. This time, you can also shoot video. Editing and sharing tools let users make the most out of the high quality VGA video they have taken.

If you are tired of pressing your fingers against the screen, then control your iPhone through Voice Control, a feature that enables phone users to call contacts simply by saying the name of the person or play music just by saying the title of the song. The new iPhone also houses a digital compass application which automatically reorients your maps to match the direction you are heading.

Since iPhones are known for its multitude of applications, Apple has now made it possible for users to copy, cut, and paste words as well as photos in between applications. What’s even better is that you can actually copy and paste images and texts from the web.

For the sporty type, iPhone has a built-in Nike + Ipod support. This means that you can purchase the Nike + Ipod sensor into your Nike shoe and you can start working out while monitoring your progress through your Iphone.

Perhaps the best feature of the Iphone 3GS is the Apple’s MobileMe service. This support service will help you find misplaced units simply by logging on to the service site (me.com), where you can view a map which shows the approximate location of your handset. You can play an alert sound though the site or remote lock it with a passcode.

It’s hard to imagine that a single device can have so many purposes. And it’s almost magical that the iPhone 3GS can do all these. It’s really an all-encompassing device, an effective tool in these modern times. However, these are just some of the applications that can be installed in the handset. There are still hundreds of useful applications in the Apple App store that can cater to every user’s needs. With an iPhone 3GS in hand, you’ll have everything you needed one touch at a time.

There’s no doubt that the Apple iPhone is one of the best modern gadgets to date. Its large display that delivers crisp images and myriads of colors are equipped with a responsive touch interface – these features make it a favorite handheld device for both casual consumers and power phone users. Perhaps the best thing about the iPhone is that applications or “iPhone Apps” can be installed. All you have to do is purchase an application at the Apple Online Store and then install it to your unit. These applications range from games to document reader.

But with the advancement of technology comes a greater risk, which is why iPhone users should give enough attention on their iPhone security, especially if their handsets are “jail broken.”

Actually, the term “jailbreak” means that the handset was “unlocked,” so that users can install custom-made applications from third party developers. These apps are not available on the Apple App Store. They are not officially recognized by Apple. But most users prefer to have their handsets unlocked to maximize its use, not knowing that these could post a lot of problems in the future.

It’s a good thing antivirus softwares like the VirusBarrier X5 can be a potent solution for phone virus and malware issues. Both iPhone and iPod Touch can be at risk so antivirus software is really needed for added protection. All the users have to do is to connect these devices to their Mac (some antivirus software actually works for PC) and scan them using the antivirus software.

Those who download a lot of applications have greater risk of malware and virus infections. It was only recently that the “Ikee” worm virus has spread on iPhones, especially on the jailbroken units that have SSH software installed. A picture of an ‘80s music icon is shown automatically as a wallpaper with a note that states, “Ikee is never gonna give you up” – a pun on Rick Astley’s eponymous 1987 hit, “Never gonna Give You Up.” This is actually iPhone’s first major virus threat and is believed to have originated from Australia.

This worm virus attacks the handset through the SSH software. But the key here is the changing of Apple’s root password. Experts have observed that the virus can only affect the iPhones that still have default root passwords. So to prevent this virus from spreading, users are advised to change their default password in SSH. The first thing they have to do is to install the Mobile Terminal through Cydia. Once installed, they can now run the program. Then type “su root” and press enter. It will prompt you to type in the default password, which is “alpine” (after which, press enter). Then type your new password (type it again to confirm).

Hackers will always find a way to create potent malwares and viruses so caution is necessary. If an application does not come from a reliable source, it’s best not to install it in your unit.
