昨天想升级ios5.0.1固件，但总是提示“错误3194” 不管是删除74.208.10.249 gs.apple.com，还是添加74.208.10.249 gs.apple.com，或者是# 74.208.10.249 gs.apple.com，又或者是安装最新版的iTunes都不能解决此问题,无限3194，我泪奔了，上网找了好久的解决方案，重启了N次电脑，最后用这方法成功了 希望对你们有帮助
下面提供最终的解决方案！
以下是hosts默认文件，替换全部保存即可【需要重启后生效！】（hosts文件路径：C:\Windows\System32\drivers\etc)
# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a ’#’ symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
注意：win7用户可能因权限问题无法修改，此时应右键hosts点击“属性”> 选中你当前登录的用户，点“编辑”> 选中你当前登录的用户，找到“权限“并且勾选全部，点应用，然后确定。即可修改hosts。
