I have a 32GB 4th Gen iPod Touch. Over the last few weeks low memory warnings keeps coming back. I wiped the iPod to only have movies and music on it since I have an iPhone 5 and iPad Air. Currently I have about 2GBs of music, 6-30 minutes shows and a 2HR Movie. I have 12GBS of total on the iPod, Well each morning I wake to a low memory. I can hold home and power button to restart it. When it comes back up there is a 15GBs available. Next morning it starts over again. It's sits on I believe 6.1.4 the last update. Has anyone had this happen? Any thoughts? Is it worth wiping again?
