Is 8GB enough memory for the iPhone 4?

So, I'm undecided between the iPhone 4 8GB. I have an iPod Touch 8GB and I never had to erase memory but I only have 2.8GB left.plus I only have 100 songs. How much memory can 8GB hold? I have on my phone 2000 pictures, 350 songs, and 20 apps. I really want the 4S but, its a little on the expensive side, does Sprint have the 4 in 16GB?

Added (1). All i'm planning on having is a lot of pictures, around 500 songs, and 50 apps MAX, I mostly only use Insagram and Twitter.

That really really really depends.

Are you planning to do many videos and download game apps?
Then you need more

Or small apps and pictures?
That all you'll ever need.

P.s Music takes almost no room at all.until you get into the thousands.

Depending on what kind of apps you are using, there are some massive ones out there. But you SHOULD be fine with 8gb, but that totally depends on what kind of apps you are downloaded, there are apps out there that are more then 1gb.

It really depends if you like taking a lot of pics and downloading lots of apps 8GB will not be enough if you stick to just using it as a phone and that's it then you'll be okay you won't need a lot of memory but I would go with a 16GB iPhone 4s sorry to say but they only sell 8GB iPhone 4 new on any network maybe with more gigabytes on eBay

Probaly not. Maybe it might make it with 16 GB. You should probaly go with 32 GB.
