What are the advantages and disadvantages of iphone 3? ?

As a mobile phone, iPhone can be said to concentrate all the investment of Apple in mobile phones, and the product line maintained by only one machine of Apple iPhone has a fairly high share in the field of smart phones. For people who have just met Apple iPhone, the gorgeous interface can attract almost 9% of people's attention, and the hearsay "App Store" can provide tens of thousands of software, plus ideas such as multi-touch and gravity sensing, which is really quite attractive. According to my experience since I used it at the end of October last year, the advantages of Apple iPhone are mainly reflected in the following aspects: 1. The touch screen operation is extremely smooth, and I have used HTC diamonds at that time, and the feeling of that touch is very different ... 2. Web browsing is very easy, which is largely based on the smooth operation, and a large number of software provided by software stores are different from MSN and QQ. Facebook, Twitter, Picasa, Flickr, these popular network applications fit very well. With 3G and WIFI, all kinds of network applications can be said to be perfect. 3. Multi-touch and gravity sensing make the entertainment function of Apple iPhone quite powerful, and this powerful entertainment function makes Apple iPhone surpass other mobile phones by a great distance. However, Apple iPhone has many shortcomings, such as: 1. The default system lacks many basic functions of other mobile phones, such as MMS, such as copy and paste, such as tape recorder. 2. The Chinese input method of the default system is not easy to use, and there are problems with handwriting and pinyin. 3. Because of the performance limitation of Apple iPhone itself, all programs can't run in the background except the phone and music playing functions of the machine, which leads to not only that you can't hang QQ, but even when a text message comes in at QQ, you have to quit QQ to reply to the text message. (The problem of answering text messages can be solved by installing third-party software after jailbreaking, which will be mentioned later.) 4. The system is too limited by Apple, so if you want to realize some functions, you must rely heavily on third-party applications after jailbreaking, such as Cydia, and applications such as Fetion have not yet had a perfect solution. 5. Software stores seem to provide thousands of softwares, but few of them are of real practical value. Moreover, good softwares are often paid software, which is almost impossible for domestic users to pay. If you want to use these paid softwares, you must use a lot of pirated ones. 6. In fact, the biggest problem is that in the domestic parallel market, the water of Apple iPhone is very deep, and the problem of unlocking SIM card leads to an endless stream of JS, and the versions in various places are also very complicated, which will be discussed in detail later. For some shortcomings of Apple iPhone criticized by many people, I think it is actually nitpicking, and many people also follow suit, such as MMS, tape recorder, copy and paste, which can be provided by third-party software, but it is troublesome because the default system does not. Short standby time is also a common problem of smart phones. Personally, I feel that Apple iPhone is still worthy of its price. At least, those so-called "Apple iPhone killers" have come out.
