You really should.

The problem is that with the app companies out there upgrading their apps to be compliant with iOS 7, you could find yourself letting the apps update but no longer be usable as they're no longer able to work on iOS 6.

As for your space issues, go into iTunes and back up your phone (music, pictures, apps, app data, etc) and then do a factory reset. This will give you an empty phone that will allow you to download and install the new iOS 7.

The space is only needed for a short term. It's basically the space that is needed by the installation files WHILE the upgrade is taking place. Once everything is done… The files are deleted to give you your room back.

It's what I had to do with my iPhone 4 8gb.

Once the update is completed, you can restore your phone or take the time to put back on the phone only what you need/want. It's a good time to decide "Do I Really use this app?" and choose whether or not to keep it.

The nice thing is that if you later decide that you really wanted it… Once an app is paid for… You can download it as often as you like. Even years since you got rid of it.

  • Should I update my iTunes even though i still have iOS7? I have an iPhone 4 so I can't get iOS8. But lately iTunes has been sending me messages asking if I want to update, but they're all meant for iOS8. I don't want to download it and have it mess up my phone somehow. But at the same time there are security updates that are usually important. So what should I do?
  • Should i update my iphone 5 to ios7?

  • Should I update my iphone 4 to ios7? - 1 I've had my iphone 4 for 2 years, it runs pretty well. I heard some people had really bad problems when they updated their iphone 4, but I also heard other people's phones were fine.
  • Should i trade my white Droid Razr for a white Iphone 4 8GB? Both in good shape. Never had the iphone and really wanted the 4s but this is my best offer. Said i could jailbreak it to make as good as 4s for the most part?
