A Brief Introduction to the Apple iPhone 4S Technical Features

The iPhone 4S caught many by surprise, with Apple expected to release the

iPhone 5 - but instead we got an iPhone 4 with overhauled innards.

While the masses were initially disappointed, the iPhone 4S features a glut of top-end tech that is designed to put it on a par with the likes of the Samsung Galaxy S2 - but does it manage to do that?

The changes to the iPhone 4S are easy to document - the camera has been upgraded to 8MP (with an improved aperture ratio), the CPU is now the same dual-core A5 processor as seen in the iPad 2, and a seven time increase in graphical processing power.

Check out our video of the iPhone 4S in action - is it the

phone for you?

Also we've got Siri, Apple's voice recognition service - will this be a game changer for mobile phones or will it be nothing more than a gimmick?

As we've mentioned, the iPhone 4S is almost identical in outward design to the iPhone 4, which might irk those that like to show that they've got the most up to date device from Apple when out and about with friends.

However, the flip side of this is that things like the plethora of iPhone 4 covers on the market at the moment will still fit.

Apple has slightly changed the design of the iPhone 4S somewhat though, by changing to a dual-band aerial design, making sure it doesn't encounter an embarrassing repeat of antenna-gate we had to endure with the iPhone 4.

For all those that haven't seen the older version of the phone, we'll take you on a tour of the new handset: the top of the iPhone 4S houses the power/lock button, as well as the headphone jack, plus a microphone for noise cancellation.

The right-hand side of the phone is devoid of any buttons, but holds the slot for the micro SIM card, which pops out using the included tool (or a paperclip).

The bottom of the phone is pretty standard, with the Apple connector and dual speakers which pump out the (actually quite decent) sound.

The left-hand side of the phone sees the rounded volume keys, with the top one of these also acting as the camera shutter button to make it easy to snap with the new iPhone. We've also got the silencer switch too, which has been slightly moved upwards from the previous iteration.

As you can see, Apple has altered its antenna band technology to move the gaps that plagued the iPhone 4's reception to a less-touchable location.

How to Find Out If My Old Accessories Work With My iPhone 3Gs

The shape of the case on the iPhone 3GS physically is a little thinner and smaller than every iPhone that came before it. As a result of this, certain accessories that worked just fine with your older iPhone may not work at all with your 3GS. However, other accessories continue to work because the actual device input on the bottom of the iPhone is the same.





Step 1: Place your iPhone 3GS onto a docking station or into a device, such as a case, car mount or other similar accessory. Some accessories that are designed to the specifications of the case dimensions on older iPhones likely don't work with the iPhone 3GS, but this is not universal. If your iPhone feels loose inside a case, won't stay in a car mount or doesn't fit on a dock, the accessory doesn't work with your iPhone.





Step 2: Check for your iPhone's battery to charge. If your older accessory is designed to provide some type of power connection to your iPhone 3GS, such as an FM transmitter, car charger or other similar accessory, it also charges the iPhone's battery. If the iPhone 3GS seems to fit onto the accessory but the battery doesn't immediately begin to charge, the accessory does not work with the iPhone.





Step 3: Push the data cable connection into the data cable port on the bottom of the iPhone 3GS. Any older accessory that isn't designed to work with the case of the iPhone and plugs into the bottom should have no problems working with an iPhone 3GS or even a newer model, such as the iPhone 4.

Iphone 3G - Black screen

Yesterday I had a very annoying problem with my Iphone 3G. Suddenly when trying to get it out of it's standby mode it shortly lighted up and froze. Just plain dead. I couldn't get it to respond anymore.

I regard the Iphone as the best mobile phone I have ever had. With all the different applications you can download from the appstore it's getting even better and better. Sound quality is also better than I ever wished. The only bad point is the battery life. But this is about the same with all other phones as well, when you are using push email on the phone.

But despite beeing good, a frozen iphone is not good. If you have to rely on your phone, for example when using it for business, this can be a real issue. You have to be sure that the phone works all the time. It is not allowed to freeze.

When my phone froze, I was afraid that the iphone was really dead. That it wouldn't work anymore and I would have to get a replacement, which of course would take several days... I was very happy when I found out how to solve the problem with the frozen iphone. Nonetheless this is unacceptable and should not have to happen.

I tried to press all buttons and all combinations of them, but nothing helped. When I came home I connected it to the electricity net, but that also didn't help. No reaction. Completely frozen.

Finally I connected it to my computer and realized it did get a connection to Itunes. That's good, but doesn't really solve the problem of the frozen iphone. Still the display was black.

If you get the same problem, here is what helps:Connect the Iphone to your computer. Make a backup of everything on the Iphone.Press Power and the "square"-button at the same time. Hold them pressed more than 4 seconds.While still pressing the square-button, let the power-button go. Hold it for at least 10 seconds (I had to hold it longer)Itunes comes up and connects to your Iphone.Make a restore. Be sure you make it as fast as possible, otherwise the Iphone is going to lock up again.ITunes will take you through the procedure of restoring. You will get all your contacts, sms, emails, programs and more reinstalled.

I found it very annoying... if it happens when you are a long way from your computer, you have no telephone! I hope Apple will solve this problem as soon as possible.

iPhone 4S Users Guide

The iPhone 4S replaced the iPhone 4, featuring many improvements over the iPhone 4, including Apple's A5 chip and a new operating system, iOS 5. The 4S also includes Siri, a voice-activated personal assistant, and the iMessage free messaging system. The iPhone 4S has numerous features you'll want to learn how to work with, in addition to basic processes like placing phone calls.

Step 1: With the 4S's built-in Wi-Fi, you can connect to available networks to browse the Web at higher speeds than you can achieve through your carrier's 3G network. To connect to a wireless network, tap the "Settings" home screen icon. Then tap "On" next to "WiFi." Tap "WiFi" and then tap the network to which you want to connect. Enter the security key or password, if requested. Turn Wi-Fi off when you aren't using it to preserve battery life.

Step 2: Siri, a voice-activated personal assistant built into the iPhone 4S operating system, answers general questions and helps you find driving directions and information about restaurants. To open Siri, tap and hold the iPhone's Home button. Tap the speaker icon on the screen and speak your question or request. Siri responds after the phone processes your voice.

Step 3: You can sync an iPhone 4S to iTunes to transfer and back up apps, games, music, movies and photos. To get started, connect your iPhone 4S to your computer and open iTunes. Click the iPhone's name under the "Device" sidebar and tap "Sync." Click "Eject" when the syncing process completes.

You can also sync the iPhone's content with your iTunes account without hooking it up to the computer. To do so, connect the phone to the computer and select "WiFi Sync" under the "Device" column to turn the feature on. After ejecting and disconnecting your iPhone 4S, you can wirelessly sync it by tapping "Settings" then "General." Tap "WiFi Sync" and then tap "Sync Now."

To sync by Wi-Fi, the iPhone and the computer must be connected to the same wireless connection.

Step 4: Apple's iMessage feature on the iPhone 4S lets you send free text messages to any person using an iOS 5 device. To get started with iMessage, tap the "Settings" icon and then tap "Messages." Depending on your settings, you may be prompted to enter your Apple password. Verify that the icon next to "Messages" reads "ON." If not, tap the icon to turn the iMessage feature on.

Open the green "Messaging" app on your home screen. Tap the "Write" icon in the upper right corner of the screen to compose a new iMessage. Input the user's email address or telephone number, compose your message and send it. If the user isn't using an iOS 5 product, you'll be given the option to "Send as SMS."

How to Set the iPhone Wallpaper

Wallpaper on a computer or cell phone adds a nice, decorative touch, just as it does in your home. Traditional computer wallpaper often portrays images of sandy beaches, falling autumn leaves or other scenes of nature. On the iPhone, you can set the background to similar pictures, or you can personalize your wallpaper by using photos downloaded from your computer.

Step 1: Plug the included USB cable into both your iPhone and your computer. The iTunes program will automatically open.

Step 2: Check the box to sync photos between your iPhone and your computer. This information appears on your computer screen when iTunes opens.

Step 3: Use the photo pane to sync the iPhone with pictures you may want to set as wallpaper. They can be in iPhoto, Adobe Photoshop or individual folders within your computer.

Step 4: Point your iPhone at the item or person you want to photograph.

Step 5: Tap the camera icon with your finger and hold the iPhone steady as the picture is taken.

Step 6: Name the picture file so you can easily retrieve it to set it as wallpaper.

Step 7: Click the "Photos" icon. Some icons may be hard to determine from the pictures on them, but are clearly marked underneath.

Step 8: Select the picture you would like to set as your iPhone wallpaper.

Step 9: Tap on the button that looks like an arrow inside a rectangle (a checkbox) and choose "Use as Wallpaper."

Step 10: Size the wallpaper photo by manipulating it back and forth within the touch screen until you have your desired shape and size.

Step 11: Touch "Set as Wallpaper" to create your wallpaper.

Step 12: Choose wallpaper from a selection of pictures already installed in iPhone if you do not want to use your own. Go to "Settings" and pick "Wallpaper from Home Screen" to select an image.
