iphones camera roll reset and archive old photos?
 

Just got a new iphone 6s (up from 5)

Is there anyway to
1) reset the camera roll to start from 0001.jpg like on a new phone
2) move all the existing (old) photos from the current camera roll to like a backup, archive folders? (There are some old photos I want to have access to on my phone, but I found having them in the main camera roll is messy)


I found the photos numbering very confusing right now, since I went from a 4->5->6s. (restore from last phone)
The img # only goes up to 9999.jpg, but I've had over 18000 photos taken, which means a lot of the photos # are repeated, often more than once.
I selectively deleted most of the old photos after downloading it onto my PC, but kept others as I want them on my phone.

btw, I thought #2 could be easily solved by creating a new album/folder, and moving all the old photos there.

But apparently, the album/folders thing is retarded..it doesn't actually move photos into the folder. It kept it in the camera roll, and if you delete it from the camera roll, it will also disappear off the folder you created.
basically it works more like a label filter than an album folder.

use a 3rd party software such as ifunbox and create a folder elsewhere other than in the camera path? not sure if you need to have a device thats jailbroken.
