Paperless caching?

I really  neeeeed an i-phone with a geocaching app!   In an effort to reduce paper waste, last night saw me cutting and pasting myriads of geocache co-ordinates and descriptions into a single Word document.  We like to have a fair few caches to choose from when we head off to the hills but with the weather dictating where we go and a dearth of any portable internet devices, we’re reliant on paper information for a variety of all weather cache locations.  But £35 a month for a fancy phone that aids geo-cachers?  I don’t think so! Back to the keyboard!
