What gb does my iphone 4 have?

Hi. Can 6ou help me. Not sure what gb my iphone 4 is. I'm on general and about and it says capacity is 13.7 gb and avalible is 9.8 gb.

32gb to check go on settings general about

It's obviously 16GB. 2.3 GB is used up on complicated technical stuff.

Its a 16GB iPhone 4. Though your phone has 16GB of internal space, 13.7 GB is the space you can use and now that you've installed apps, music, videos etc you have 9.8 GB of space available.

It's 16GB.

A 16GB. A simple check in iTunes would have shown this as well.
