I've recently obtained an iPhone 5 so this question may be one of ignorance. I am trying to install apps but am not having much success. I do not have good cell service where I am located but I am connected to my home wifi. I am able to launch the app store and search for the app I want. I believe that implies the wifi connection is working and being used. I touch the "get" button and it changes to "install". I touch install and there is a very brief display of the circle icon (almost can't see it, it is so brief) then the "get" button reappears. That's it. This happens with all the apps I've tried. Am I doing something wrong or is there some setting somewhere that is wrong? TIA.
