Should I buy more gb for my iPhone?

So I have an iPhone 4 and I did not upgrade to ios 7 yet. When I tried to it says I have to have 3.3 gb of space. Well, I need more space so I got ready to buy some when i got confused. My iPhone is not connected to the iCloud backup- I think it is connected to the iTunes. If I upgraded my storage plan would it give more room for my phone overall or just to the iCloud?

Just the icloud. That's one of the reasons I ditched my iphone. Every other phone has expandable storage.

You can't add physical memory to your phone.

  • Will buying more iCloud space let me download more apps, songs, and photos? So i have deleted apps that i don't really need and deleted songs i don't listen to but still there's not enough space to even take a photo, A pop up comes up that says to manage my icloud storage. Would purchasing more icloud storage allow me to download more apps and have more songs and pictures on my iPhone 4 from sprint? It is an 8gb i think.
  • Which iphone should i buy? Should i buy one or an ipad? Pro's and cons of an ipone? I'm 15, and I use to have a phone but I got really bored with it so I got rid of it, I don't want to get an iphone then get bored of it do you think i will find them boring. How much credit internet should i get for my plan? People of said get a iphone 4 or 4s coz the iphone 5 doesn't charge properly, so I don't really know? But I want to get an ipad and really can't make up my decision, which one is better in the long run?!
  • More you use an app the more space it takes up on iPhones and iPads? I have an iPad and new iPhone 5 that I just got. I have rhapsody on both the same app and amount of music basically (iPad as seven more songs on app) but on the iPad the rhapsody app takes up 2.8 GB and the iPhone takes up 1.8GB. Why is that? The more use the app the more space it takes up even if you're not adding new content?
  • Should i buy more icloud storage? On my iphone i have pretty much completley run out of room. I can't take anymore pictures, no video, no shows on itunes. And i really need to use imovie but i don't have enough space to create a new project. Will buying icloud storage fix this?
