iphone4 sux balls big time out in the bush. I go into the Rockies with mine and it is so depressing that the GPS won't work there where the cell signal is weak or non existent. Maybe an app would help? Runkeeper seems to work even when the GPS won't so I don't know why that is. What kind of wildlife noises are you trying to record? Sounds fun!
On Wind $39/mo unlim everything plus US roaming. Son on Wind $35/mo unlim everything. Husband still on Rogers $35/mo text/voice. Such a ripoff. He's switching soon.
