So I recently had an iphone 4 16gb but i dropped it and it broke, instantly becoming unresponsive. I called apple and they sent me another iphone 4, however it was an 8gb instead of 16 because thats all they had left. I was given the option to pay $100 and upgrade to a 4s 16gb, but i am wondering if I should stick with the free 4 8gb. So I have done the math and I will only have about 5 apps, and because of what the apps are that takes up about one half of a gigabit. when you take that, as well as the space taken up by iOS, you are left with anywhere between 5 and 6 gb. Well I would have no music on the iphone, as I use Pandora, and no music videos, movies, or t.v. shows as well. Now with all of that being said, about how many pictures do you think it would take to fill up the remainder of space?
