How to clear loads of space on an iPHone?

I need to clear lots of space to get iOS7 but don't want to delete loads of music. Any help would be greatly appreciated.

Connect your iphone to itunes and just uncheck stuff that you don't want.

Take a hammer… Smash it. Buy a phone not made by Apple.

  • Why doesn't any space clear up after I delete an app from my iphone? It doesn't matter what software version or app I have because it just makes sense that if an app takes up 4.3 MB, when you delete it and restart your phone 4.3 MB should be available.
  • Trying to clear space on my iPhone. What are Documents and Data? Hi, I'm running out of space on my iPhone and it says most of my GB are used up by "Documents and Data"… What items make up the Documents and Data category? So what should I be deleting to make room? Ex; if I had way too much Audio I would delete my music. What's "Documents and Data"?
  • My Wi-Fi is recognized by my iphone 4, and loads but won't connect. How can i fix this? I have an iphone 4, and before my home Wi-Fi would connect instantly, but now when i go to my settings, the Wi-Fi keeps loading and loading, but the check won't appear. The Wi-Fi sign turns blue, but no check! It works on my PC, and my siblings andriods, but not my phone. I've tried everything, reseting the network, turning my phone off. Nothing seems to work. I'm using my 3G now.
  • My mom and i got the same phone and same plan yet her internet loads all the time and mine never does? Two iPhone 7+. Same unlimited data plan. Yet literally no matter where I'm, nothing that uses data loads unless I'm connected to Wi-Fi. Yet my mom's internet loads no matter where she is. It's even happened that we're in the same place trying to load the same thing and hers loads while mine doesn't. Yes, I have my data turned on. I've made sure all my data settings are identical to my mom's. So i really don't know what could be causing this.
