Old iPhone not enough storage to update?

I got my phone in February 2012, so it's pretty old. It's an iPhone 4. Revert I haven't wen able to charge it because it's running such an old version of iOS that when I plug it in it says "charging not supported with this accessory." I would download the latest iOS but it needs 3gB of storage to install and I only have 200 mB free as my phone only holds 6gB total. If I delete all my photos, download the later iOS, will my original storag be back or will I never have room for photos in my phone again?

For Starters It's been about a year It's not that old. I think you may just have to delete stuff and you can update it.

Don't update your IOS using your phone. You better use itunes to update your IOS.

If it is a big update then you will not have room for the photos and you can't get them back.

  • Why does my iPhone 4S keep saying there's not enough storage? My 16gb iPhone 4S keeps popping up with a little box saying there's not enough storage every time I try to take a picture. I'm travelling atm so not being able to take pictures is pretty annoying. I have previously deleted loads and loads of things to make room for all my travelling pictures and I just don't understand. I've tried resetting it, is there anything else?
  • What do i do when my iphone says it does not have enough storage? It says that i don't have enough storage to update my apps. I deleted a few videos already. And i don't have much apps. How do i make it so i can update them? Plus i have an ipad thats connected to my iphone, but still the same mail comes through and everything.
  • Not enough storage to update to ios 7 with iPhone 4? I have an iPhone 4 8G phone. I've deleted almost all my apps and pictures/music and I still do not have enough memory to download the update. Why is this update so large? I've seen some of my friends phones and the system doesn't seem a lot different then the weird design
  • Not Enough Storage' Pop-Up on my iPhone 4S won't go away There are two options, 'close' and 'settings'. I tried to press them and niether of them do anything and won't go away. Now my phone is locked. I can't turn my phone off, pick up calls, or even slide to turn it on. How do I make it go away?
