I recently bought my own GPSr (the one I used to get started was borrowed) but no matter how hard I tried I couldn't justify spending a couple of hundred quid on an all singing all dancing unit, so no paperless for me
so I turned to the internet and googled like mad, found a few apps that looked good for mobile phones but as my model does not have gps (nokia E63) most of them would not work and I am a cheapskate and refuse to pay hahahahahahahaha
Then a friend of mines was visiting (nearly converted muggle) and asked if my phone read PDF files. I had no idea so we tried this anyway ..........
If you use a free programme called Cutepdf (The perfect price for me)
http://www.cutepdf.com/products/cutepdf/writer.asp
you can convert the cache description page into a pdf
-click the print cache link (you should get the printable version)
-select file-print at the top of the page (or Ctrl+P)
-select CutePDFwriter as the printer (print preview page)
-go to my documents (the cache PDF should now be there)
-and drag and drop it to your phone (took me a couple of attempts and I had to make a folder on my phone so I could find them)
I hope this will be of some use to someone else and help to save them carrying loads of paper round with them
