I tried http://www.geocaching.com/seek/cache_de ... 81b733a701, downloaded version for Pocket PC and ran on HTC Desire Android 2.2. After initial quest and filling of first answer ("1420") I chose the T2 option, which lead me towards a location. I had 1 location and 1 item in inventory. Once I reached location, I also got a hint, that I'm actually INSIDE of the location, but nothing happened. There was no task to perform. Is that my wrong understanding or is it incompatible cartridge? Did I do anything wrong?
