Interesting observation.
Kind of like this new "formula" they are using for diplaying the bars. They spread it out, which is good, but they also made the lowest bar display at a lower dBm. So where an android or 4.0 and prior iphone will show no bars, it will now display 1 bar.
I've been messing around here with twistedfocus' iphone 4 and my nexus, and heres how i feel about the whole deal. Yes, they put the antenna in the wrong location. The bottom left isnt the only wrong location, anywhere on the outside of the phone i think is the wrong location, especially with these types of phones where you will be holding them in landscape or portrait mode. How it made it through testing I dont know, and thats the biggest screw up apple did, along with denying that there is a problem and that people need to hold it differently.
My phone will drop ~25dbm when I cover up the antenna, which is about the same what the iphone does. Only difference is I have to do a lot more than just touch it.
