Anyone use this app? I've tried Mobile GMaps about 6 times now and each time it works great for a few days and then stops working. Once it stops working if I turn off the BB and restart it, the app is gone entirely. It doesn't even show up in the application listing. I give up on it which sucks because I liked it better than BB Maps and Google Maps. It's supposed to be free but it sure acts like a trial version that removes itself after a few days.
