I don't know if this is to do with this subject? I've bought a tiny gadget, one phone USB at one end of 3" of cable and one normal-sized USB socket at the other end with a USB plug inserted. I had to provide a small SD disk (I don't think I've used the correct description?) to plug into it. It now works like a zip drive that I can use between easily between my phone and PC.
It only cost me £5 from a local phone shop.
I've started to use it by downloading various documents to it, like my rucksack carry list, etc. Not sure yet if it has potential to be of benefit to me when Hiking? I haven't tried yet but I think I will be able to download maps and photos to it which will then display on my phone screen or display on my PC. If you already own one, any suggestions about how best to use it?
For example, is it possible to download an app to it, like LastPass, so I can keep this app off of my phone completely until I actually want to use it?
