Took it out for a little geocaching spin today. One-sentence summary - inadequate in many ways, but software development will probably cure much of it.
- The accuracy of the GPS seems fine. I suspect that some of the physical limitations the phone faces due to the size of the unit (as compared with the size of the 60csx or Colorado) are being well-compensated for via the cellular corrections. I guess it is worth noting that the last iPhone had cellular-based location gimmicks that did a pretty decent job, without using GPS technology at all. I hunted for two caches today trying to rely solely on my phone, and other than a couple of times when the "me" beacon seemed stuck for a few moments, it seemed pretty good. It wasn't very happy when I passed through some tree cover, but then again, my Garmin isn't often overjoyed either. When I was standing on the cache, I was virtually standing on the cache. However, this brings up the point that...
- I have concerns about how good the GPS technology will be in an environment with no cellular coverage. I myself am probably only in an area with no cellular coverage twice a decade. But I know many of you behave differently. I don't have a great sense of how accurate the GPS would be in that environment.
- Currently, the applications for hunting caches pretty much blow. The only application I have on my phone that is GPS-helpful is Google Maps, which is okay but not great. You can't zoom in nearly as close as I'd like to zoom (designed with drivers in mind), it won't show you distance to target (at least, that I could figure out) or tell you want direction to go. And you can't cut and paste the GPS coordinates from the browser page to plug them into Maps. Argh! But that said, it will take GPS coords as an input, and will drop a pin exactly where you tell it to. Once you get used to just trying align your "blue dot" with the cache's "red pin" without the other information, it really wasn't a bad experience, and not fundamentally different than following looking for a cache from the map page on a Garmin. Because Google Maps doesn't store information locally - it retrieves map and satellite info from the web - this may also be a case where using your iPhone to cache outside of AT&T's coverage area would pose a big problem. The unit knows where you are but might not be able to really show you where you are on a map, unless I'm missing something.
- That said, a program did get released today in the iTunes store called Geopher Lite that is the first caching program for the iPhone that I can identify. Its heart is in the right place - it will pull up caches near you based on your current location, tell you your current location and how far your are from a target, display a compass, etc. What I like best about this program is not necessarily what it does or doesn't do (some of the reviews were pretty negative), but rather that Apple approved it for listing in its iTunes store. This seems to mean that the hand-wringing over their developer agreement (much of it by me) is not really a concern, and real-time geocaching applications are fine by Apple. I would expect better and better products to come out in the coming months, ala the different options currently available on the Palm OS (GSAK, etc.). Even this program is only advertised as a "Lite" version, so maybe the full version will be a lot better.
- The point about taking the iPhone out in inclement weather is fair, but I think that there are certainly solutions. I have a protective arm band I slip my iPhone into for running that provides some padding should the phone be dropped, a protective plastic window for the screen that still allows touch screen inputs, and can be attached with a strap to your arm or leg while you hike.
- Logging from the field is cool, should you want to do that. As much better as the browser is on an iPhone compared with my Treo, I'm far less happy typing on it than I was on the Treo's physical keyboard. I can double-thumb that thing and go reasonably fast, but the iPhone's touch screen keyboard is trickier, and for me, a lot slower.
Overall I wouldn't think about getting this phone to replace a GPSr. But if you are getting this phone anyway, you might not feel like you have to bring your GPSr everywhere. I usually keep my Garmin in my bag in case something comes up, but I don't think with this phone I'll have to keep doing that.
