Should I update my iPhone apps?

Some updates are just bug fixes and stuff. My bro recently told me he doesn't because it takes up memory. So if I update will it fill up my phone? I kinda wanna update but now i'm unsure. So should i?

Updates are meant to keep apps current & safer.
They don't necessarily take more memory.

If you don't update, you'll probably encounter a lot of problems with them (crashing, slower, etc).

Yes, and it doesn't take up any more memory then it would if you didn't update them.

If the updates are bug fixes but you have no issues then I wouldnt update, thats what I do since its not crashing anyways or having any issues. If its something added, then I usually will update it.

  • 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.
