Does anyone use (or is it possible to use) an iPhone to upload their flight logs to the OLC? Thanks.

Where is the IGC file? If you are using an iPhone app to generate it, I believe that app would need the built in facility to upload (iGlide for example). iOS 10 does not have a Finder, or File explorer, or otherwise user exposed file system. iOS 11 is supposed to have this facility. I believe Android has had it nearly from the beginning.

You can of course tether your iPhone to your computer and upload that way.
