I have notepad in my iphone 3 and now I want to install wattpad in my iphone, because I have heard that this is free writing iphone app for iphone and it features authors from all over the world, fan fictions, stories, one shot, so many different things. But whenever I am trying to install it in my iphone, “unsuccessful installation” note comes on the screen. May be I am making any mistake. So can anyone tell me how to install it in my iphone 3?
