Of course apple offers the 16g and 32g but rarely are they ever exact. I guess it's hard to fit all those bytes accurately into a device? I don't know. But anyway I bought the 32 gb model of the iphone 4 My iphone 4 has 29.06 gigs. That's almost 3 whole gigabytes that aren't there. Thats a lot of content. I have already about 26 gb of movies and music on my itunes. So that doesn't leave a lot of room even though I got the biggest model possible. But at least my phone is awesome! It's just a little frustrating. Anyway, please post how many gigabytes your iphone 4 ACTUALLY has.
