● WCDMA role of the geometry?
3G version of the iPhone compared to iPhone’s biggest difference is the generation of cell phone frequencies to support WCDMA.
WCDMA uses Direct Sequence Spread Spectrum Code Division Multiple Access (DS-CDMA), Frequency Division Duplex (FDD) mode, chip rate 3.84Mcps, carrier bandwidth of 5MHz. Based on Release 99 / Release 4 version, available at 5MHz bandwidth Within the user to provide the highest data transfer rate of 384kbps. W-CDMA can support mobile / portable devices for voice, images, data and video communications, the rate of up to 2Mb / s (for the LAN case) or 384Kb / s (for the broadband network is concerned). The input signal is first digitized, and then in a wide spectrum within the encoded spread-spectrum mode of transmission.
3G version of the iPhone to China is a disability. Powerful network function to China useless, finally catch up with a 3G, the result was TD’s. To which a function of amount spent could never get it is really extremely depressed, this iPhone into the Mainland followed by the generation of iPhone is almost no difference.
● the price is still attractive enough
See the 3G version of the iPhone, many Apple fans will exclaim: “wow! Too cheap, only 199 U.S. dollars ye! 200 U.S. dollars less than!”
But now stored grains offer us know? Produced using the 8G flash memory cards generally offer 200 yuan, 8G also read and write speed of around 400 yuan.
● iPhone flood did not personality
iPhone at its birth, even though expensive, still captured the hearts of a lot Tell me. Now iPhone is filled with a! Really can not imagine that originally were hoping to get to show off what the iPhone, with the others, oh, the collision is extremely embarrassing.
This is due not only expensive to buy, and now the price so cheap you can buy it? No way to! So many people when they are expensive to buy, and now become cheaper, that does not even spring up all over the! And the colors are monotonous.
● If you want to use GPS have to another Jiaoqian
Perhaps you will say: “Give me a break, GPS satellites on the line as long as there is simply no need to spend a penny.” Yes, GPS itself does not need to spend money, as long as the outdoor search satellite navigation could be achieved. But that is what you say N95 or N82. 3G version of the iPhone is the built-in A-GPS, although it has also a kind of satellite positioning, but with the Nokia, Dopod and other navigation mobile phones can be very different.
Although the A-GPS positioning accuracy, but it must be transmitted over the network through multiple (up to six one-way transmission), this operator is considered taking up a lot of air resources. AGPS main problem is that users are using mobile phone location service to be replaced difficult to accept. And AGPS mobile phones than the average power consumption of an additional burden on certain indirectly shorten the phone’s standby time. Said the simple point is, A – GPS positioning need to go through GPRS networks, while the cost of GPRS traffic enough to make you crash.
● Standby increase was Tim doubts
In theory, increased battery capacity, or optimization of mobile phone standby time will have increases. 3G version of iPhone is also true, according to statistics, the new iPhone’s standby time to 300 hours, talk time from 8 hours to 10 hours. From that point of view alone, iPhone change is tangible and worth admirably.
Although the standby increase, but another problem emerged. After optimization of the new iPhone battery standby time is enhanced, while video and music playback time is not increased, can play music and video using the battery power is not? This feeling is very difficult to understand.
● shell beautiful, but easy to wear and tear
Generation of iPhone when available, many people on whom dumped. It was elegant appearance, cutting-edge technology, as well as clear the screen martini wine, like fireflies in the dark, then the clear-cut so dazzling. Can be used for some time, the outer layer can be scratched a lot.
A new generation of iPhone to the users new hope. Then against all expectations, 3G version of iPhone case is still not much different from the previous generation. Although the body back into the black, but the piano paint fingerprints brought trouble and difficult to eliminate wear and tear, will allow 3G iPhone in the near future become a “big Erhualian.”
● can not expand storage space
Although the 3G version of iPhone built-in 8GB of storage space, the general ordinary people used to store songs and movies is almost enough. Should the hit film, but mad, music madman. 8G of space can be inadequate. Today’s high-quality album up a lot of space, a clear film do not talk to hundreds of M, calculate down, it can not keep a few films.
Yes, if the 3G version of iPhone could also have memory card expansion slot, then it is the storage space can be greatly enhanced, and now 4G, 8G card also has a lot of money to spend can be purchased, but also very cheap. Do not support the expansion of 3G version of iPhone must have a major weakness bar.
● equipped with Bluetooth can not pass the file
Bluetooth is used to ask why it? A passerby said: used to songs, and Lu Renyi said: used to transmit documents. Yes, Bluetooth mobile phone from the early high-end configuration will, and now almost every cell phone will be configured, we can say is a major leap forward. We walk in the street will often see people using Bluetooth headsets, Bluetooth around often been used to transfer files. The only normal for us, the. However, for iPhone, this may be somewhat difficult.
Yes, because Apple’s insistence on copyright protection, iPhone Bluetooth will only give you wireless music, but can not be used to transfer files. If for some good songs, friends want to share with you, excuse me, go find yourself bar itself. Music to pass, however. Because the iPhone does not support Bluetooth file transfer protocol, only songs. The 3G version of it? Remains the same.
● Music Store into a decorative
iPhone In addition to a good screen and innovative modes of operation outside the network function is also very strong. Built-in music store to provide users with a variety of audio and video album. If you like what the first song, just the Internet, through a simple purchase can be downloaded to your favorite music, can be said that very convenient.
But music store to the collapse of our country, and not because of poor management, but can not operate. Put aside all the costs of networking, say the cost of purchasing music on the people too much, people that the ah, but according to U.S. operators. And if they can connect to the Internet and that is also a brawl with the flow of money leaving the country again.
● second-generation iPhone is really 3G phone?
Perhaps this point is for foreign clients say. 3G version of iPhone support for WCDMA. As we all know, Europe and the United States is already quite well-developed communications network, data transmission speed is high. Video call is already a commonplace in general, and Hua Fei are reasonably cheap. This is our country than not, although the trial operation of TD has been the network, but will take some time to enter the formal.
Since the 3G version of iPhone support for WCDMA, then the video call is an essential element. But I do not know Apple’s intention to do this, or ignore this point. Through the issuance of the picture can be seen, this iPhone is not even a front facing camera. Is it time to make video phone calls right back and do her face? Is really puzzling.

More iPhone users free IMAP Push Mail service, set to become a civilian version of BlackBerry. YouTube also added iPhone, one of the default software to enable video playback into iPhone’s strengths.
Nokia’s Design Director, Alastair evaluation iPhone
Alastair: iPhone touch screen, this is actually Nokia has been exploring an aspect of the design of Nokia, which in previous years has been reflected. In our industry, not just an iPhone to do this exploration, we are concerned about, but also in previous years to be reflected in Nokia products. Its benefits and advantages that enable better interactivity. This is not just for the design itself, but makes computer interaction more friendly.
2 questions, first, I do not think iPhone will be the impact of the listing of our design concept, our design philosophy – “human-oriented design” will not change; second, we have designed for consumers as a core take into account consumer demand, the first observation, after the design and understanding of consumer behavior, the consumer first place. There is our beautiful design mobile phone to use them. Yesterday, I mentioned that environmental concerns, including sustainability. I feel like Apple is not doing such a traditional phone company, has entered the mobile space, but also a good thing, that we in this industry is very attractive. In some respects, our design concepts are interlinked, and some aspects of Nokia’s unique. We feel that Nokia’s design concept that we are proud of one thing.
