My IGC files get written to an SD card. I thought maybe I could connect a card reader to my iPhone and use that to upload but that may not be possible.

I use a HooToo thumb drive to copy files to the iPhone, then export to DropBox. Safari recognizes DropBox as a source of files to upload to OLC.

If you're stuck with a SD card, then I'm sure there's a product that allows you to transfer to the iPhone/DropBox for upload to OLC or any other website.
