Should I update iPhone 4s apps?

I have an iPhone 4s and woke up this morning to 20 updates available in the app store… They're obviously all for the iPhone 5. Now since the iPhone 5 has a larger screen… Should I update my apps? Maybe this seems like a dumb question but I don't want to update then not be able to play any games because I can't see half the screen…

Always keep your phone and apps up to date.

If the only update is larger screens don't update. But if they have something else eg bugfixes update them

It is beneficial for you If you update your apps.

  • Is the iOS 6.1 update on iPhone 3 safe to update? On my first iPhone there were problems, and the update didn't help it wiped out everything and among other things had to get a new iPhone. The iPhone I have now works, so should I risk this update? It's a 3GS.
