No 3G icon display even if connected to Wi-Fi
I am currently considering downgrading to iPhone 4, if possible. Since the version 5.0.1 I am using is denying me access to some of the most basic services. For some reasons that I don’t know of, I am unable to connect to the internet even if I am connected to a particular Wi-Fi. There is still no 3G icon that is usually at the top of the screen. When I tried the social sites apps such as twitter and Facebook nothing happens, yet the other apps such as iTunes safari or mail work well. This is really strange and I don’t know what to do as I have never been in a similar situation before.
What does this mean? Is there some setting that I should change?
