Earlier today when leaving work I got stuck in an elevator. I was in there for maybe 45 minutes before the elevator company came and got me out. If I didn't have my iPhone 4, I would have never made the call to the super to get someone to get me out. My older 3G never had reception in this elevator -- not even a bar. The whole thing about iPhone 4 can't make calls is a crock and this is a testament to that. Amen!
