http://www.tuaw.com/2010/07/06/iphone-4-reception-issues-a-network-reset-might-help/ TUAW and boy genius posted this earlier today. Before resetting my network connection, I could not "drop the bars" on command. It was a hit or miss, sometimes I could do it, sometimes I could not. All test where done while sitting at my house in downtown denver, 4 blocks from an AT&T tower according to the Atttowers.com site. While I was in the same boat as most, brand new iPhone 4 with a loaded backup from my 3GS, i reset my network settings and can now "drop the bars" on command with the slightest touch to the lower left "black strip". I dont know what this means, but it's not good.
