It's a bit late in replying, but thought I'd put in my two cents worth. My husband recently got a Storm2 and added Geocache Navigator to his phone...a second paid version. We've linked both to our team geocaching.com account. So if he's traveling on business and wants to find geoacaches there he can. We've tested it and it does work. I'm not sure if you had one paid version of GN and trying to use it on two phones or two phones and one GN.
