iPhone固件说明和使用

iPhone固件说明和使用小编有话说：本文主要让读者了解iPhone各个版本的区别，查看方法和升级方法。

iPhone使用的是特别定制的Mac OS X操作系统，发售初期自带系统版本为1.0.2，之后以固件更新的方式修正低版本的错误并且引入新的功能。

下面是一些关于固件的相关知识iOS 4.0.1版固件新增功能1、修复信号强度计算公司及显示效果2、修复其他潜在BugiPhone 1.1.1版新增功能1.新增短信铃声设置2.新增的“HOME BUTTON“设定功能3.新增漫游时关闭数据连接的功能4.新增进阶影片播放选项及TV OUT输出功能5.新增iTunes WiFi Store 支持在线购买音乐6.修正话筒和喇叭的声音，声音变大了7.修正在1.0.2版時，当从睡眠状态启动时，画面会有停滞现象，减少了死机现象8.修正某些程序运行速度，比起前一版來說的确变快了iPhone 1.1.2版新增功能新版本在1.1.1的基础上增加的功能不多，最主要的是增加了多国语言的支持。

iPhone 1.1.3版新增功能1.1.3固件加入了短信群发功能、网络短片观看功能、Google Map定位功能以及九宫格操作界面等。

除此以外新固件还为iPhone加入了更多语言种类的支持iPhone 1.1.4版新增功能1.1.4主要修正了1.1.3的一些BUG，提高系统的稳定性iPhone固件版本查看方法如果你是新机未激活状态的话，请先将iPhone开机，然后滑动滑块，在紧急拨号键盘中输入 *3001#12345#* ，在出来的“Field Test”界面中，点击“Versions”，那么“Firmwareversion”后面显示的就是你现在的版本号。

（如果你的机器激活成功，可以直接在Settiing → General → About中查看Modem Firmware即可）1.0.2固件：对应的Firmware version是03.14.08_G1.1.1固件：对应的Firmware version是04.01.13_G1.1.2固件：对应的Firmware version是04.02.13_G1.1.3固件：对应的Firmware version是04.03.13_G1.1.4固件：对应的Firmware version是04.04.05_G固件升级方法（一）、如何用iTunes升级以下操作需要把iPhone链接到电脑（1）iPhone的升级有两种模式：第一种：“恢复”，这种模式会删除iPhone上所有的资料，恢复所有的系统文件，并把iPhone 恢复到非激活状态。

iPhone史上最全的使用教程

iPhone史上最全的使用教程iPhone的解锁、越狱、激活、固件等等是什么意思，有什么分别这几天看见好多新人问这几个词的含义及区别。

我在这儿说说我的看法，不是官方解释，不懂的学习一下，懂的绕道，如有错误，敬请指正！第一次买来时或恢复官方固件后，iPhone会处于那种只能拨打紧急电话状态，不能使用其它功能，如果要使用其它功能，就必须进行一项操作，那就是“激活”。

一般有锁版的只有使用对应运营商的卡（如美国的AT&T卡）或者无锁版使用任何卡，才可以激活。

激活之后就可以使用其它功能了。

有人说：“放屁，老子用的美版，移动的卡，怎么从来不用激活就可以使用啦？”这里就要说到“越狱”，一般来说，有锁版的不签约用户，可以不激活，可以不软解，但不能不越狱！越狱主要有两个作业：第一就是使用破解软件和第三方软件，第二就是绕过官方的激活操作（具体原理不清楚，不知是绕过还是欺骗，希望高人指点）。

什么叫“软解”呢？“软解”是“软件解锁”的简称。

那什么叫“解锁”呢？解锁解锁，解的是网络运营商的锁。

为什么为什么这么牛叉的手机AT&T才卖你$199?就是因为有这个锁！锁住这个牛叉的手机，让你只能用他的手机卡，让他挣钱！就像移动心机只能插移动卡一样，不能使用其它运营商的网络。

可是有些国家法律规定：“不许搞技术垄断，消费者是上帝，他想用啥网就用啥网，只要上帝给点钱，你就必须能让他使用其它运营商的卡！”于是“解锁”就诞生了。

怎么解锁是运营商的事，上帝们只要付钱就行了。

比如澳版等！还有个词叫“无锁”，就是没有网络锁！比如官网订购的港版！无锁好啊无锁好，就是价钱受不了！还有些国家法律不保护花钱的上帝们，比如美国。

想买无锁？下辈子吧！于是一些牛叉无比的上帝们开始钻研，他们就是DEV Team ! 他们做了个“软件解锁程序”，这就是大名鼎鼎，无比牛叉的“YellowSn0w”，可以不通过运营商就可以“解锁”，于是上帝们省钱了。

2. 按键盘Shift +恢复，弹出一个对话框，选择下好的官方固件，点确定恢复官方固件。

3. 恢复完后将iTunes关闭, 运行redsn0w.exe，点Browse，选择3.12官方固件后打开，点Next继续；选择Install Cydia，有锁机再选上Unlock，点Next继续；解压下载好的bootloader，点Browse，3.9 Bootloader选BL-39.bin，4.6 Bootloader选BL-46.bin，选完确认无误后点Next继续；先将iPhone关机，关机后点Next继续；然后按着Power 键保持3秒，随后同时按着Home键保持10秒，直到iPhone 黑屏后保持按着Home键，松开Power键，10秒后松开Home键，iPhone便开始加载越狱文件，加载完后点Finish 完成，iPhone将会自动重启并完成越狱与解锁工作，等待完成后便大功告成。

iPhone日期设置1970年1月1日变砖了怎么自救

iPhone日期设置1970年1月1日变砖了怎么自救近期iPhone上出现了一个很有趣的现象，如果你想让自己或者好友的iPhone变砖的话，只要把他的手机上时间设置为1970年1月1日即可。

具体操作方法就是设置完日期之后，将手机关机重启，你的iPhone就有99%的概率变成一块砖头（请慎重尝试）。

这种方法导致的变砖即使是你进入DFU模式都无法刷机重启，只能找苹果售后解决问题。

目前已经得到证实的是，凡是运行64位的iOS 8和iOS 9，以及使用苹果A7、A8、A9和A9X处理器的平板电脑都有可能遇到这一问题，32位设备目前还是安全的。

重点是小编还真的有朋友不怕死，实际验证了一下。

在时间手动设置完成后，重启手机并进入Apple Store。

这台iPhone瞬间就挂掉了，无法恢复，无法启动，变成一块砖头。

那么怎么办呢？所在地方没有苹果旗舰店只能快递了吗？小编教大家两个方法，可以解决问题：1.拆机拿掉电池，等一段时间（大于10分钟）之后重新安装。

这个方法对技术要求较高，手残党慎重操作。

2.如果手机电量以及时间都充足的情况下，等待数小时，当Unix时间戳的数值大于等于0，系统的时间就会生效，这个时候就可以正常开机。

（这方法完全拼人品，无法保证绝对能恢复）3.最后实在没有办法，只能找苹果售后了。

给大家附上如何触发这个漏洞的方法。

进入设置——通用——日期跟时间，关闭自动设置选项，之后手动将时间调整到1970年1月1日。

设置完成之后，将手机关机，重启然后进入apple store，这个时候我们会看到你的iPhone 已经损坏，无法恢复无法启动，手机变砖了。

一些reddit用户在猜测，出现这个问题的根源在于时区的调整。

在iPhone可以回退的日期中，这个数值超过了iPhone的默认设置，不被iOS认可，因此出现故障。

但是目前苹果官方仍未对这个问题作出任何的解答。

小编在这里忠告大家一句，不要随意尝试，一旦变砖，人品不好的情况下你就只能带着手机去找苹果售后了。

【中考英语易错题】易错点01 名词(原卷及答案)

易错点01 名词易错考点【01】词义辨析在中考中，对于名词的考查，更多集中在具体语言环境下名词词义的辨析上。

结合中考，可以看出，多数学生出错，是由于没能准确掌握形（义）近词的细微差别，或不善于结合具体语言环境中加以辨析，而导致失分，建议单词默写时，能做到看英识汉，看汉默英，结合语境，灵活运用。

．．．．．．．．．．．．．．．．．．．牢记：只有把单词放入语境，单词才有灵魂。

易错考点【02】可数名词的数可数名词数的考查，中考永恒的考点，而学生错误，更多的是对于特殊单词的复数变化规则掌握不牢造成的。

如：不规则变化，单复同形，同形复数与规则复数的意义变化，国人复数的变化等。

建议多背多用，借助口诀，巧妙记忆。

可数名词变复数的不规则变化fish鱼sheep羊deer鹿“某国人”的复数形式：中日不变英法变，其余S加后面。

中日不变：a Chinese- --two Chinese a Japanese---four Japanese英法变：an Englishman --- three Englishmen 3个英国人其余S加后面: a German- --five Germans 5个德国人易错考点【03】不可数名词的量出错原因，主要是由于单复数不能正确区分，或对于不可数名词量方法掌握不牢。

突破方法：变复只变计量单位。

可不可数区分口诀：名词分两半，能把原名叫，就是不可数。

如：water, 分成两半，还是water,所以是不可数名词。

易错考点【04】名词所有格记牢名词所有格的不同表达法。

's口诀：分别所有分别's，公共所有最后's，s结尾只加'。

学生失分的主要原因，是对所有格加‘s的规律掌握不牢固，或是不能通过语境来确定是公共所有还是分别所有。

A 12-year-old boy from Hunan invented a new kind of window because of his _________.The window can prevent children from falling out.A.c ommunicationB. celebrationC. honestyD. creativity答案详解：由于句意没有理清，容易出错。

什么是iphone 越狱 Microsoft Office Word 文档 (2)

一越狱1) 什么是越狱，为什么要越狱？大家刚拿到手机的时候，安装软件唯一途径就是从苹果网上商店中下载，免费的有但没几个有用的，更多是要付费的。

打个比方就是你买了正版的windows系统，用的时候，发现咱还要花钱买正版的office,正版的media player，正版的这个那个软件；即使有别人做的免费软件或者第三方软件，windows也不让你用，必须它授权才行（授权可以理解做提成）。

所以我们就需要越狱了，这样干了后，大家可以自由的下载安装任何想要的程序到自己的i4中，不受限制--类似我们现在使用windows然后随心所欲的装软件一个道理（先声明俺不支持盗版，俺只说国情）。

2)越狱有风险么，越狱还是不越狱啊？越狱有一定风险，这个主要是使用的越狱软件有可能不完善造成的，但只要细心点，找到合适的越狱软件就ok了。

还有就是往往很多情况并不是越狱本身造成的--很多人越狱后过于兴奋，见软件就装见游戏就下，这才产生问题，试想你给自己windows装上乱七八糟几百个软件，你看它能不出问题么!所以回答是当然越狱了,稍小的风险换来全新的用户体（越狱前越狱后完全两码事），你说干还是不干呢！对于越狱伤机的说法，我个人认为完全不用担心。

实际上越狱行为应该是一种软破解，即通过手段给用户自由安装软件的权限。

越狱后安装的软件（ipa）和在苹果在线商店买的软件同样都是mac os上的可执行程序，执行方式没有任何区别。

而越狱以及越狱后装软件的最坏结果是系统崩溃（不乱搞基本不会出现），用itunes恢复可以了(大侠如果是有锁版的i4请注意版本问题)，不会造成机器本身损毁；原理同大家使用windows软件一个道理：我们平时用windows误操作或者中毒什么的，什么时候造成电脑本身烧掉或者损毁的，无非是重装系统罢了。

总结起来：一切都是软（软件）的，不是硬的（硬件）！实际上，可能让机器损毁的是通过软件对芯片进行误操作，如读写某些寄存器“故意”让硬件以异常方式工作，发热或造成其他方式损毁。

如何利用苹果手机进行办公

如何利用苹果手机进行办公随着科技的不断进步，越来越多的人开始使用苹果手机来进行办公。

其实，利用苹果手机进行办公已经成为越来越多人的选择，不仅方便快捷，而且还能提高工作效率。

本文将从苹果手机的办公应用、设置个性化工作方式、配件选择等方面来讲述如何利用苹果手机进行办公。

一、苹果手机的办公应用苹果手机上的App Store中有众多的办公应用可以选择，比如微软的Office套件和谷歌的Google Drive等。

其中最为常用的三大套件包括文档处理类应用、协作办公类应用和邮件客户端应用。

1. 文档处理类应用：苹果手机上可以使用iWork来进行文档处理，包括Pages、Numbers和Keynote。

这三款应用用来分别处理文档、表格和演示，具有高度图文处理能力。

而且能够直接在iCloud上同步使用，并且还能与微软Office套件进行无缝链接。

2. 协作办公类应用：苹果手机上除了自带的邮件应用外，还可以选择Slack、Asana、Trello、Notion等协作办公类应用。

这些应用可以帮助用户管理项目、任务以及团队合作。

3. 邮件客户端应用：苹果手机上可以使用自带的邮件客户端应用。

在设置中添加公司或者个人的邮件账户后，就能够进行邮件收发了。

不过如果邮件量比较大，还可以下载其他邮件客户端应用，比如Mailspring和Spark等。

二、设置个性化工作方式为了更加高效地进行办公，用户可以使用苹果手机提供的一些操作来进行个性化的设置。

1. 使用Siri语音搜索：Siri是苹果手机上的智能语音助手，能够帮助用户关注任务，可根据用户需求查找各种文件，让您免除手动搜索之苦。

2. 利用记事本管理任务：苹果手机自带了记事本应用，用户可以直接在里面添加待办事项，方便自己对每日任务的管理。

3. 开启热点网络：若没有Wi-Fi环境，在需要上网的情况下，用户可以在苹果手机中开启热点网络，即可让其他的电子设备便捷的连接上网络，快速处理公务。
