I just updated my iTouch OS (and temporarily lost all my apps and data - recovered now) so that I could then installed GC.coms latest version of it's Geocaching app.
Sadly, the ability to access and download your own uploaded gpx files from GC.com has been overlooked in this version, and that was the one feature of the app that I used everyday. It's a noted oversight they are 'investigating.'
They HAVE included the ability to put a downloaded cache (singly) into whatever 'list' you choose. About time.
They still have not included a way to search for a cache quickly in any 'list.'
Closer to Geosphere, but still far from as user friendly. They have relocated the buttons for various features just to keep you further confused.
That tantalizing 'Send All' button must be what keeps iTouch users buying this app. Geosphere is far better for in-the-field data management.
