I am using iphone 3g. I used to have skype mobile phone app in my phone but I uninstalled it because of some reason. But now I want to use the Skype service again in my phone. So I have restored the software in my phone. But now when I am trying to install it in my phone, it says that it requires IOS 4. So can anyone help me solve this Skype iphone 3g software problem?
