I own the iPhone now and am rather disappointed with its lack of possibilities.... Too bad its gonna take a second one to fix everything. I can't decided between it or the google approach w/ the Android software... quite frankly its gonna b the one who can deliver my application. I'm leaning google since it will all be open source which leads me to my point. I REALLY WANT TO GEOCACHE WITH MY PHONE. So whoever makes the best geocache/app features wins my heart cause can u imagine, getting the locations from your phone only to enter them into your phone to find! Truly paperless!
There actually was a geocaching application on the iTunes store for all of 12 hours. But then the developer requested it be taken down do to Groundspeak stating he did not have permission to utilize the geocaching.com website in a paid application.
I think the best we can hope for now is an application created by Groundspeak them selves which they will most likely charge a decent premium for.
I also use my blackberry for impromptu geocaching drips during lunch at work or right after work. However, the application I use is a subscription service. The name is eluding me right now, but it is quite handy to have a geocaching device in your pocket at all times.
Wow I just tried geocaching today for the first time! It's pretty cool. I just wish the app didn't cost so much. $10 is a little high...I just used the website and google maps, but it was kind of annoying.
