Been using the Cachesense app on my BB Bold 9780 since October, for me it seems more accurate than my gpser and the app has loads of cool features.
Aside from PQ's and logs, I like the ability to use the compass or a radar finder, plus field notes, etc. Now I find myself leaving the GPS at home, but I always have my phone with me, and I have lots of local caches stored in it, plus PQs for upcoming vacations and/or road trips.
My only question now is, for an upcoming trip to the Caribbean, since I'm going to turn my data plan off, does my in-phone GPS still work (satellites, right ?) ??
