It sounds like you have a couple of issues here. I have a smartphone (Apple I phone 4) and I love it. I have the geocaching app installed on it and it works great. For geocaching purposes I don't think you can beat the gps. I have a garmin map 76CS and it's ok and I also have a Delorme PN40. I really like the PN40. If money is the issue maybe you should upgrade the phone.
