Today the new version 4.0 has been released. This brings a completely new developed geocaching.com communication and many new features.
One of them is quite interesting: If you have geocaching friends in your address book and set their geocaching name as their nickname, you can call them from L4C. It is possible to filter all downloaded logs of a cache for friends and geocachers in the address book. Finally Telephone Jokers 😉
