When I changed the language, it worked for about a day then same problem again, just said loading
This time my Internet connection also wasn't working
I searched problem with Internet connection and came up with somebody suggesting to reset network settings
My son did this for me and I haven't had any problems with the Internet or App Store since
Hope this helps you also
This is my third iPhone (3G, 4S and now 5), I have never had any issues with my other phones and am a bit disappointed. I'm not very tech savvy so have found these few issues very frustrating, thank goodness for my teenage boys
