So I have been on the road doing my book project and have been all over the North and Western part of the country. I have been in the high country of Tuolumne Meadows and in lots of places that have poor reception and in *every* single case, the IP4 has been equal to if not better than other iPhone users or verizon users reception and ability to web browse. I have had not one dropped call, even with one bar. This phone seems to lock on a signal and not let go. I have even produced a short film of wildlife in Glacier National Park all on this little phone. Our film crews using Red series video equipment was stunned at the quality, especially when a wolverine came bounding into a scene of Big Horn Sheep, all edited on the phone. Overall, I am 100% satisfied with this phone, use it with a bumper, simple soft rubber back case and will use the Otterbox Defender when I pick it up from home in a few weeks when we take a break. In the real world, this thing just rocks!
