Most of you hate that daily popup to update to the newest firmware. I know that I do. Well to stop this all you need is 5 mins and a app from the AppStore.    

1. Get iBlocker from AppStore 
2. Open iBlocker. 
3. Go to block urls and click the white arrow. 
4. Click the + in the top right. 
5. Now add this URL to the URL section http://mesu.apple.com 
6. Name it update or anything you want. 
7. Click save. 
8. Now click the + again. 
9. Add this URL to the URL section http://applednld.apple.com 
10. Name it update 2 or anything you want. 
11. Click save. 
12. Now make sure all toggles you have made are on. And you will now have no daily update prompts from Apple!
