How to update iphone apps without appstore?

I have some apps on my iphone that i want to update, but there's no appstore on my phone via restrictions. I have tried updating them from itunes on my computer but that does not work either because of restrictions. Some people said i should jailbreak, but i don't think i can because again, i can't access appstore or safari…

If there's anyway to update these apps let me know please.

You don't, they come from the appstore.

  • Why isn't Minecraft LITE in the Appstore for iPhone 5? When I went to look for Minecraft, all I got was Minecraft PE. And I checked more games by the developers and they only had Minecraft PE as their game. When I was in the apple store, I saw an iPhone 4s and it had Minecraft LITE but why doesn't the iPhone 5 have it?
  • Why does the appstore say that the app is incompatible with my iphone? Okay my iPhone 3gs has an ios of 4.2.1 i downloaded apps that is compatible with that ios so why does it say that it is incompatible with my iPhone. My iPhone is up to date or updated. WhY? I downloaded the apps through iTunes and when i sync my iPhone to the computer then put the apps in it it say it is incompatible with the iPhone! Why?
  • Why can't I log into the AppStore and update or download apps? Every time I try to download or update an app it's stops it right away, so I looked it up and it said to sign out restart your iPhone and sign back in then it will work. But I can't sign back in or download or update my apps. What can I do?
  • Where do i change the credit card for my iphone on the appstore? I bought something on my iphone with what i thought was my credit card but i checked my balance afterwards and saw that the balance hadn't changed. So that means it's charging someone elses card and not mine. How do i change what card it charges?
