What's the difference between and iphone that has 8G, 16G, and 64G?

I want to get the iphone 4 now that its cheaper, but i don't know which one to get. What does all that mean? Which one should i get? Which ones good?

Each number represents the amount of space the phone has for videos, games, movies, apps, etc. From 8G being the least amount of space, to 64G which has the most available space.

That is the size of the hard drive. I have an android phone with 8 Gigabytes (G) and that is plenty because you have access to a cloud storage (free internet storage) where you can store pics and stuff. Personally, I would go with the 16G if it isn't significantly higher in price, but 8 GB is a lot of storage space still to you. I have not come close to filling up my 8GB and I have a ton of applications and all my pictures upload directly to my dropbox account, which in free online storage.

The difference is the memory. The more memory you have the more things you can put on it.

The g stands for gigabytes. It's the amount of storage space. I have a 64g iPhone 4S, and I really like it. I can have basically as many apps, photos, songs, videos, etc. As I want because it can hold so many files. If you don't plan on putting much on your phone, you may want to go with a version that holds less because it is cheaper. It all depends on how much you want to put on your phone

It's the amount of stuff it can hold. I got a 4s with 16gb yesterday. My 2nd gen iPod Touchwas an 8gb and I still have tons of space on it (I bought it 3 years ago)

8g dosnt have much memory
16gb is good for iPhone not iPad
Their is a 32gb I'd recommend that
And the 64 gb Is huge
