Hi, I am using iPhone 8GB (First gen) and am getting iPhone 4. I was almost decided on 16GB till my friends told me that 5 megapixel photos will be much larger than 2 megapixel ones. Also HD video will be large. I am only using 5GB out of my 8GB phone now. I have 3GB of music and about 600 pictures on my phone. And yes about 150 apps I dont need movies or TV shows. So just for Higher resolution pics and video, do I need 32GB over 16GB? Some advice would be great. Thanks.
