Hi, I downloaded a app on app store but it's completely useless so everytime I hold the app, it doesn't show the "X"
IPhone 4s: How to delete a undeletable app that I got from App Store?
Yeah you can't do anything about it. Apple is all uptight about their stuff and won't let you modify it in any way. I hate it, but that's what you get with an Apple product. You could jailbreak your iPhone, but if it's only to get rid of that app I wouldn't recommend it.
