Should I get a 32 or 16gb iPhone?

Virgin mobile is now only selling iPhone 4s in 16gb and I don't know if that will be enough but I really don't want to pay $200 more just for an iPhone 5 so I can get the 32gb. Could I get some people with those capacities to tell me how much they hold?
I currently have a 32gb iPod touch with 600 songs, 43 videos, 2994 photos, 44 apps and 8gb remaining. I was thinking I might be able to get away with the 16gb iPhone 4 if I delete some movies and limit my pictures?
Could I also get some opinions on the iPhone 4 and 5?

Added (1). Could I get some more answers to the question I actually asked please? I've already decided I'm getting an iPhone.

Get a Samsung Galaxy S4! IPhone's suck!

Get iphone 4 it's cheaper lol who cares about Siri?

If you want to save the $200 just keep carrying your itouch. Why give up what you're already used to?

  • Will a 16GB iPhone 5 have 16GB of space? I want to get an iPhone 5 and the 16GB will suffice, however I'm concerned about the actual space. I have a 32GB iPod Touch but according to iTunes the maximum space available is 28.5GB. Could I expect this sort of thing to happen on the iPhone?
  • What iphone 5 should I get 16gb or 32gb I'm upgrading from my iphone 3g… Yes its been a while lol. I take alot of pictures somewhere around 1500 on my phone now but thats only a 3 mp camera, and if i had a video on this there would be alot of videos taken. I also have a couple apps and like 500 songs. So since i don't know what the spage is like with better cameras and better graphic apps that take up more space I need some help. Should I go cheap and get the 16gb or the 32gb?
  • Should trade my iphone 6s 16gb to get an iphone 6s 128gb? Or wait for the iphone 7? I waited to late to trade it in so now ill have to buy a whole new phone? Should i wait for an iphone 7 or just go ahead and buy a new one with more gb.
  • Should I get the 16gb or 32gb iPhone 5? I currently have an 8gb iPhone 4 and I plan on upgrading to the iPhone 5. I'm just not sure how many gb's I should get. On my iPhone 4, I have 20 songs, 7 videos, 4, 000 photos (I know, alot!) and 57 applications. I have 700mb of free space left. Price is not the issue. I'm willing to pay the extra 100 dollars. I'm just not sure if I should or not. What do you think I should get?
