IPod 4th Gen 8GB vs iPhone 3G 16GB?

Well I got a iPhone 3G at a garage sale cheap as. But my dad has a iPod 4th Gen, and I can swap with him as he wouldn't mind having the iPhone. I have a Samsung Galaxy Mini, and it is my preferred phone, but a severe lack of storage hampers me. I wouldn't use the iPhone for 3G internet or anything, just calls (maybe), that and apps. I can't fit Facebook on my current phone, but the 3G can't be upgraded past 4.2.1 or something, meaning Facebook for a start can't be installed. There are older versions of these that I know where to get, and my question is which one should I take? I fear 8gb may fill up too fast, I'd mainly use it for music and Apple exclusive apps.
All you have a good night.
