Satisfied iPhone 4 user.
I'm on my second iPhone after dropping my first one. I brought it into the store and they replaced it on the spot. It's was in a case but landed on a pebble. My wife and I both have the new iPhone 4 with no dropped calls or signal loss(again we have cases). We are completely satisfied. We even traveled from San Francisco to Texas with no issues. Just wanted to post some positive news.
