    Unable to update iPhone 4 to iOS 5.1 software.

    I want to update the iTunes software from 4 to itune 5.1 but during the process of updating the problem occurs. I have tried these through the iTunes and also my phone but I can’t get either to work. When I try on phone the error occurs. Message occurs when I try to download from system. There was a problem downloading the software for the iPhone the network connection fails to establish. I was thinking that is there any solution for updating from my phone or the computer?

    While in my case changing the DNS worked. These are the steps that I followed with my iphone.
    1) First select the setting.
    2) There you will find general.
    3) Then select network.
    4) Then you fill find WiFi(select current wi-fi network).
    5) Touch the blue arrow button.
    6) At last change the DNS # to 8.8.8.8
    7) Then go back to the software window option which is your general window.
    8) Right away the update will be starting.

    I am having the apple TV.to update the process the steps are the same. Select Settings then General>Network>Wi-Fi (select current wi-fi network)>touch the blue arrow button> change the DNS #. But the DNS name you have to provide is different i.e. DNS# 208.67.222.222 and 208.67.220.220. The main frustration comes because none of the DNS changes are permanent.

    Try changing the DNS server on your router.
    1) In my network places on the desktop select properties.
    2) If the option is not available in the desktop then select start then my computer there you will find the network places select it. Then view network connection.
    3) Locate the network connection that is associated with the internet. It may be something like
    "Local Area Connection”
    4) Select the properties option while right clicking it.
    5) In the general tab list select internet protocol (TCP/IP).
    6) There will be appearing a window. Select the option to Use the following DNS server addresses.
    7) There you have to enter your prefferd DSN server.
    8) Then press ‘OK’.
