So, I would like to update to a jailbroken Ios5 but my phone is filled to capacity with pics and vids. I am using PhotoAlbums+ which is sketchy at best. Has anyone else here done this successfully?

Problems: - I have 3 folders of pics. One of which comes up in Windows when I plug the phone in. - I tried to SSH into the phone to move the pics but was unsuccessful? Maybe there is a better to do this? - I have used Cydia backup apps but they were also unsuccessful.
