How utterly childess/petty/ridiculous!!!! What next 'no entry level yellow Garmin'?! No caching on a Wednesday? No caching without a degree in navigation?
Geocaching is a sport that is a DIFFERENT experience for everyone. Some seek out FTF's, some don't seek out nanos, some seek out coins, some seek out multi's, some seek out cache & dashes, for some it is a family day out, others it is their daily routine/life! Some are competitive, some do it occasionally, some use GPS units, some just use Google maps and some of us use iPhones. It is an individual CHOICE.
Firstly I appreciate the concern over iPhones but if it hadn't been for the iPhone, I would have got into geocaching. I wouldn't have bought a GPS unit to start a hobby that I might not even enjoy. The iPhone has introduced many new people to geocaching and that has to be a good thing. I can cache on a whim without having to worry about having a GPS with me and I don't need to carry any extra equipment.
I have used the 3GS and recently upgraded to the 4 and both have been extremely accurate in FINDING caches.
I do appreciate that the iPhone has it's limitations. Sometimes tree cover can be sketchy but I have still always managed to find caches in woods and the signal doesn't normally drop out for long.
PLACING caches is different. I have experienced problems with co-ords when placing caches in woods & I think this is where the real issue lies with using the iPhones so I do not feel that an iPhone is suitable for this in all places (though in fairness I have read reports that some entry level GPS units have sketchy tree cover too). Urban areas are possibly different because it is easy to cross-reference with Google maps. So people do need to be aware of this if thinking about placing caches with an iPhone and maybe this needs to be addressed by geocaching.com.
However I am totally pro-iPhone for geocaching finds and think that to place restrictions on 'who' can find it is small minded and just isn't in the spirit of geocaching.
