Is it worth updating to iOS 7 if I have an iphone 4 with only 8GB of memory?

What I want to know is… Does it require 2.9GB of my 8GB allowance of space or does it simply require some spare room for the download and then I will still have loads of memory again after the update?

Yes, it require 3.2GB for updating to iOS 7. You can transfer your music, photos, and more to the computer and then free up your iPhone.

  • Why have I paid for 8gb but only got 6? I've recently bought an iPhone 4 with 8gb but when I synced it on iTunes it says I only actually have 6gb. This is with "other" which I know how to reduce. Also on my iPhone itself on settings it says I only have 6gb. This memory is very valuable because I only have 8gb and if I'm honest I think I should have bought at least 16gb. Can you help me by answering with an easy answer baring in mind I'm only 15 and you'll probably confuse me?
  • Why does my Iphone 4 only have 6.3 GB of storage when it's supposed to have 8GB? I looked in the "usage" section and it says that I have: 4.6 GB used and 1.7 GB available Shouldn't I have 3.4 more GB available because I have 8gb of storage? I'm kind of confused.
  • Which ios is best for iphone 4, 8gb with a 2.1gb of memory free space? I have an iphone 4 8gb. Which ios is the best for my phone? Now i'm using ios 6. Sometimes it gets lagged when opening app such as line, path or instagram. Does the phone memory affect the performance too? Currently there's 2, 1 gb of free space in my phone. I don't put any musics in it. I only use my phone for communication and social media and gallery as well. Anyone know well about ios and iphone, your help is very appreciative.
  • What do I do when I run out of memory on my iPhone 4 8GB? I have about 20 or 25 apps… 260 songs. That's about it and I only have 2GB left. I add like 10 songs a month but if I keep it up I will soon run out of memory. Will I have to buy a 16GB iPhone 4 and sell my 8GB or is there some way I can get more memory installed?
