This should be something fairly easy to figure out, but searching Google doesn't seem to produce any searchable results, but I know the real experts are right here

I have hundreds of photos on my Android phone, all structured in albums, which appear as subfolders when browsing the device.

If I move the photos to my new iPhone, will Apple's own transfer app retain the folder/album structure, or just move the photos over en masse and compile them in some other fashion (ie, by date or location)?

Is there a way to keep the photos in these albums without needing to import everything into iPhoto in one huge blob then sit there for hours manually creating albums and dragging photos one at a time into the iPhoto albums to sync back to the new iPhone? I hope not, as this would be mind-numbingly tedious.
