how long is a piece of string ??
depends on the size of the images, and the quality of the video.
If its of any use (assuming your trying to decide between 16 and 32gb) the 16gb is plenty. I had an 8gb iphone and could just about fill it with photos and videos and stuff. 16gb will be plenty.
For you maybe, but I've got 50GB of music alone
Assuming 2Gb is taken up by apps about 2800 songs @ 5Mb a piece, 5600 pics at 2.5mb each or about 28.5 hours of video at normal DVD rip quality![]()
