Having problems downloading/updating apps on iPhone?

My iPhone and my mom's iPhone both are having problems the past few days downloading and updating apps. They load half way, then start with a popup that says "unable to download".It doesn't matter if you click done or retry, because it keeps trying to load either way. It's not the connection, because we've tried downloading with several different connections, but it's the same thing every time.

If your credit card info has changed it won't update or any of your info

Apple has no doubt the best technology but customer friendliness and propreitory hard/software makes it not a lovable company. In fleecing customers it is as bad as Microsoft. You have to always dance to its commands, use only Apple propreitory items. Downloading only via iTunes is the worst part… Look at Android D/Ls… How smooth and fast! I have stopped using iTunes and download all my videos on a 16 GB pendrive - can use the same pendrive with an adapter on iPad, iPhone, Samsung Tab and Bluray DVD player and also a TV or monitor

  • Will updating my iPhone apps affect my phone speed as how updating the Operating System (OS) will? Currently I'm using the iPhone 5s on iOS 8.3 I know if I were to update my phone to the latest OS I may notice some slowdown on my phone's performance, since it may not have the "muscle" to handle certain functions. Many apps now are optimised for iOS 9 and/or the 6th generation phones. Will my 5s' speed performance slow down if I update my apps? Will the app's performance slow down?

  • Problems with iphone 4 after updating it? I just updated my iphone 4 to iOS 6 but when i connected it to itunes it says that the sim card is missing. Now i can't use my phone. What is wrong?
  • Problems with downloading iOS6? I have an iPhone 4 and it gave me the option to download updated software so I did. And I've always had my email as my apple ID. And I went to download the YouTube app again and my moms apple ID email pops up for me to put the password in to download the app. And in my settings, it's set as my email. Anything reason why? Or how I can fix it?
