Just a few hours after they released iOS 4.1 beta for the developers, Apple has released iOS 4.0.1 for iPhone 4, 3GS and 3G. This is a minor firmware update basically aimed at iPhone 4 users and includes the controversial patch for mobile signal to be displayed more accurately.

Apple hopes claims that this firmware update will resolve all the iPhone 4 reception issues. Now, that we know that the press conference later today is related to iPhone 4, we are still left guessing on what Apple has to say.

    Raju U just download The software 4.0.1 And i put it to open with Itunes
    My question is how do i update my Iphone to that software..

    • Claire

      carlos,in order to install the software in iphone or ipod or whatever,you just go to itunes,and while you have your iphone connected with the pc you click the “summary” of your iphone and then there is this thing that says “Check for update”..And then,while holding shift,u left-click and then right-click!!After doing that,it’ll open the window with the software downloads u’ve downloaded and then u just click a software and your iphone will be updated!!!
      and that’s all….
      PS:I am not that good at explaining,but i hope i helped u!!!:)
