I am using iphone 4 and I am really very happy with its features. I am not seeing any problem in my 3G connectivity which I was facing in my last nokia mobile. Its touch screen is also very sensitive. I have one problem, I want to hide my keyboard after reading SMS because its reduce the visibility of my screen. Exactly it is not a problem; I am not able to utilize it properly. If anyone known to this issue please tells me all the steps.
