The Apple iPhone 3 GS Revolutionary in Technological Advancement Mobile Communications
- Pda Smartphones
It sounds very arrogant, or a mere expression of how sophisticated Pda Smartphones called iphone. And suppose it does not complete when we talk about development without talking about mobile phone, iphone supposedly sophisticated people calling as a revolutionary leap in technology in the field of mobile telecommunications that enable all your telecommunications needs plus other functions such as entertainment internet browsing, video recording and even conduct personal secretary because is equipped with office applications and many others. Then if all the sophistication of these features already meets your needs and deserve purchasing? Pda smartphones to remember this one the price is not cheap, well I think it depends on each individual person. One of the most important thing people want to buy a Pda smartphones are a variety of reasons such as ease of operation, design and a stylish form, functionality which facilitates their daily work, especially for those who are highly mobile. This is what the responsibility of Apple to launch the latest generation Pda Smartphones iphone 3 gs “the letter” S “which means speed, must be recognized it Apple has done a remarkable job in creating all the gadget lovers dream to integrate all the basic functions of telecommunications, entertainment to office applications in a single device.
Features
- The screen has an oleophobic coating. Literally meaning “fears oil”, the screen repels skin oils. It smudges less, and is far easier to keep clean. Just rub the screen with a soft cloth, and finger smudges disappear. It’s a tiny detail, but it makes a real difference.
- Apple claims a slightly improved battery life over the 3G. In our experience, it wasn’t noticeably better or worse. Those upgrading from the original iPhone should note that both 3G and 3GS have less telephone talk time, unless you disable 3G mode. The difference is dramatic: 5 hours in 3G mode, 12 hours in 2G mode.
- Though Apple didn’t even mention it, the speaker is much louder in the 3GS. Alarms, music and speakerphone all benefit. But, the headphone jack’s minimum volume is higher, too, which can be frustrating.
- Lastly, the iPhone 3GS now supports the Nike+iPod system, just like the second-generation iPod Touch introduced last year. Like the Touch (and unlike the Nano), you already have the wireless interface built in. Just buy an adapter for your Nike running shoes, and you’re set to go.
- CPU
- The iPhone and iPhone 3G used a Samsung-made ARM 11 processor clocked at 412 MHz. The ARM architecture is known for its power efficiency — some variant of an ARM design is used in almost every smartphone in the world — and the ARM 11 is a respectable processor, but it is now dated and less efficient than newer designs. The iPhone 3GS upgrades to a next-generation ARM design, a Cortex A8, clocked at 600 MHz. (The same core is is used in the new Palm Pixi.)

The iPhone 3GS looks nearly identical to its predecessor, as do the contents of its box: a USB/charging cable, a tiny wall charger, and Apple’s iconic white earbuds, with built-in volume controls and microphone. But, since iPhone OS 3.0 brings lots of new features to previous iPhones and the 3GS alike, Apple made sure that the new 3GS hardware also incorporated hardware improvements beneath its similar facade.
The 3GS display is slightly warmer than its previous version as it has a yellow/orange tint. The warm screen is easier on the eyes even when the brightness is very high. The video playback proves the claimed improved speed. It features Safari for browsing, camera working very fast as it comes with 3.0 software, and even booting the device takes just half the regular time. The apps that take long loading times like Sims 3, Metal Gear Touch and Oregon Trail… all of them work much faster. Everything is really faster than ever. It’s like switching from an old computer to the newly launched speedy machine.
Video Recording
New with the iPhone 3GS (ignoring previous “jailbreak” projects) is video recording: 640×480 video at a full 30 frames per second (roughly DVD quality). It’s super-easy and looks great. You can trim videos right on the iPhone 3GS, then email them or send them to YouTube or a MobileMe gallery. And video capture is fast, with no delay for encoding a video when you’re done; it just drops into iPhone’s “film roll” and you’re back to shooting. And iPhone compresses video for emailing (or uploading to YouTube or MobileMe) in seconds.
You can transfer your videos to your Mac at full quality using Image Capture or iPhoto. These .MOV format files are encoded with the high-quality H.264 video codec and AAC audio. Our videos were mostly around 3700 kbit/sec. but varied depending on how complex or dynamic the subject matter was. A one-minute video will be about 25-30 MB.
When emailing, the iPhone shrinks video dimensions to 480×360 and increases compression to get the bitrate down to 800 kbit/sec. The resulting video looks a bit soft, like a VHS tape played a few too many times, but it retains full frame rate. Visual quality appears to drop again when uploading to YouTube, but it’s quite adequate for the casual video typically created with cell phones.

Improved Camera
First up, Apple replaced the mediocre, 2-megapixel, fixed-focus pinhole camera of the original iPhone with a higher-resolution autofocus camera. Now sporting a 3-megapixel sensor (1536 by 2048), it also performs better in low-light situations. Apple seems to have tuned the new camera to be a bit brighter and more contrasty, with greater color saturation.
The iPhone 3GS includes several different assistive modes for the visually impaired: high contrast, zoom, and full VoiceOver. You can use these in any combination, and you enable or disable these in Settings, or in iTunes. When you’re setting up an iPhone for the first time, if iTunes detect you’re using VoiceOver on your Mac already (or GW-Micro Window-Eyes on Windows), it automatically enables VoiceOver mode on the iPhone. To increase contrast, you can invert the screen to a white-on-black scheme. This works just like the Mac assistive mode, including inverting colors — so blue controls turn orange.
But the real star is VoiceOver. While Zoom and High Contrast come over from the Mac nearly intact, VoiceOver is designed expressly for the unique iPhone interface. Since every element of iPhone’s interface can change, anything could require description. With VoiceOver, you can just touch the screen and iPhone will tell you what’s under your finger — and as you drag your finger, it describes what you’re passing over.
The new iPhone 3GS has an unusually rich voice-control interface, finally moving the iPhone up to, and beyond, every other mobile phone we’ve owned in the past decade, which all supported some form of voice dialing. iPhone 3GS sets a new standard with true speech recognition. It recognizes every name in your address book, and every playlist, artist and album title in your music library. And it just works — no training or pre-recording needed.
To activate Voice Control, you press and hold the Home button for a few seconds. The iPhone plays a tone and displays a blue screen with an animated sound wave, indicating that it’s listening. Music control is just as easy: Just say, “Play songs by The Sisters of Mercy”, or “Play Playlist Energy Twilight”. Again, iPhone confirms, then starts playing the new music. Recognition was consistently good, whether using the headphone mic or the built-in mic. It worked fine in a car at highway speeds, but we didn’t try it in an extremely noisy environment, such as a subway.

Compass
An electronic compass is built into iPhone 3GS. It seems mainly to be an aid to the Google Maps application, which can rotate a map so that “up” is the direction you are facing. The stand-alone (and very pretty) Compass app, like a physical compass, is easily thrown off by nearby iron objects and magnetic fields. Even the tiny speaker magnets of the earphones are enough to spin the needle from an inch away. A MacBook Air hard drive affects the compass from nearly four inches away.
The iPhone 3GS includes in its photo data the direction the camera is pointing (from the compass), along with the GPS location (or geotagging) data previously provided with the iPhone 3G. Keeping in mind its limitations — which includes a margin of error of a good 45 to 60 degrees of arc! — the electronic compass is a nice enhancement to Google Maps now, and we look forward to seeing what sorts of uses independent developers find for it in the future.
