How can I put pics I take on my iP4 in folders. The camera dumps all my pics into one giant "folder", but sometimes I take pictures from different parts of the day and it would MUCH easier to have some organization. For example, I'm going away this weekend to Austin and want to take pics from what we do at breakfast to noon, then another in the afternoon when we are sight seeing, then another during dinner & dusk, then another one for nightlife (honestly for nightlife, I'll break out my P&S, but still). I know I can download them to my computer, organize them in my photo app, then re-sync them to my phone, but I'll be running around on the fly. Can I do this natively on iP4? Is there an app for that?
