hell all.. i have an iphone 4 and my dad has a htc evo. we are trying to figure out which apps will work on both. we hunt together and was looking at getting a location app that we could see where each other are while in the woods. no more 2 way radios or anything. i fouind a couple that would work but thought i would ask you guys. also any cool app that works on iphone and evo would be appreciated. thanks!! im loving the evo. i may be changing if the service gets better. my iphone always has full service at the camp and the evo doesnt. hopefully it will get better soon
