联通上网卡iphone突然无法上网,求助!!跪求!
你好，iPhone手机无法上网的原因：
1.确保飞行模式已关闭；
2.检查iPhone显示屏左上角显示什么，信号有几格，5格为满。如果信号没有问题，再检查运营商后边显示什么，3G为3G网络环境下，E为2.75G，字母O代表为2G网络环境下，请尝试改变您的位置或到户外尝试；
3.上网APN参数是否填写正确；
4.查询服务器上SIM卡的上网状态是否正常，查看SIM卡是否支持并已开通NET接入点上网业务；
5.还原网络设置；
6.重新放置SIM卡；
7.恢复iPhone，确保使用的是最新版本的iTunes。下一步，连接iPhone。在“设备”下的左栏中，点按iPhone，然后点按“摘要”标签中的“恢复”。
排除以上方法，建议您换机测试，如果该SIM卡在别的手机上也不能上网，则判断属于卡的问题，可致电10010人工或者到营业厅查询卡的上网数据是否正常。
iphone 的new 怎么用
iPhone的“New”通常指的是新消息、新通知或新内容的指示。
在iPhone上，“New”一词经常出现在各种应用中，如邮件、消息、社交媒体等，以提示用户有新的内容需要查看。这些新内容可能是未读邮件、未回复的消息、新发布的朋友动态等。当这些新内容出现时，iPhone会通过通知中心、应用图标上的数字或小红点等方式来提醒用户。
以邮件应用为例，当收到一封新邮件时，邮件应用的图标上会出现一个小红点或数字，表示有新的邮件需要处理。用户打开邮件应用后，可以看到邮件列表中的新邮件旁边会有“New”标签，以提醒用户这是新收到的邮件。点击邮件后，“New”标签通常会消失，表示该邮件已经被阅读和处理。
在社交媒体应用中，“New”也经常出现。例如，在Twitter或Facebook上，当有新的关注者、点赞或评论时，应用图标上可能会出现小红点或数字。进入应用后，可以看到相应的通知或消息旁边有“New”标签，以提醒用户查看新内容。
除了应用内部的“New”提示外，iPhone的通知中心也是一个重要的新消息聚集地。通知中心会收集各种应用的新消息和通知，并按照时间顺序排列。用户可以从屏幕顶部下拉进入通知中心，查看所有未读的新消息和通知。这些消息和通知旁边也可能会有“New”标签或小红点，以提醒用户及时处理。
总之，“New”在iPhone上是一个重要的指示符，帮助用户快速识别和处理新消息、新通知和新内容。通过合理利用这些“New”提示，用户可以更加高效地使用iPhone，避免错过任何重要信息。

In 2007, Apple introduced the iPhone, which instantly became one of the most talked-about consumer products ever. Thousands of customers lined up to be the first to buy the phones, which featured computing and Wi-Fi capabilities, along with a crisp, computer-like display on an innovative touch screen. Rivals rushed phones with similar features onto the market.
In October 2011, as Apple unveiled the iPhone4S, the competitive landscape had changed significantly. Millions of people were expected to start plotting how to be among the first to buy it. But millions more may be considering an Android phone. Android’s share of new smartphone sales is now more than double Apple’s share, a striking change from 2010, when the two were roughly even, and a reflection of how Android phones have improved and become more broadly available.
Yet Apple, by many measures, still remains the smartphone player to beat, with better profits from the business, huge influence among mobile app makers and innovations that rivals scramble to copy.
The new version, the iPhone 4S, comes with a"virtual assistant," Siri, that recognizes voice commands by users to schedule appointments, dictate text messages and conduct Web searches.
Although the new phone is virtually indistinguishable on the outside from its predecessor, the iPhone 4, the company says it is packed with better technical innards, including a more advanced camera.
The phone also includes a more powerful chip known as the A5, the same microprocessor that acts as the brains inside the iPad. The company also said the new phone would run on two kinds of cellphone networks, GSM and CDMA, allowing its operation worldwide.
Prices were to start at$199 for a model with 16 gigabytes of storage. Apple will continue to sell its older iPhone 4 through its wireless carrier partners, which will drop the price to$99 from$199 when customers commit to a two-year contract. An even older model of the device, the iPhone 3GS, will be free, instead of$99, with a two-year contract.
The new phone will be available on the AT&T, Verizon and Sprint networks. Read More... Legal Dispute Soon after the iPhone 4S was introduced, Samsung Electronics said that it would seek to block its sale in France and Italy, asserting that the phone violated its patents. In

However, there has been criticism of the company's outsourcing and move of jobs from the United States to China. Apple and its manufacturing contractor Foxconn have receivedcriticism due to poor working conditions at the assembly plant in China.
