It is because your iPhone stopped up dating - I had the iPhone 4 too and all of sudden I was not getting things on the Joann's app, or my Starbuck's app, and Target. At first I thought it was the result of all my data space was used up, so I dumped a lot of old pictures and some apps I was not using and it didn't help. I do think it is Safari that prevents the updates. I got some odd messages telling me that I didn't have the current operating service and as a result couldn't up-date.
Supposedly there is a class action case going about the Iphone4, since it forces people to replace the phone since it won't update. I didn't want to wait so went with the iPhone 6.
