iPhone 4 signal problems do exist, but not serious

We do iPhone 4, iPhone 3GS, and the Nexus One of the signal comparison test. The results show (the lower the signal data in the table the better)), in most cases, iPhone 3GS the best signal, but with protection cover at the time, iPhone 4 signals to be slightly stronger in the Nexus One, even in Poor signal conditions, iPhone 3GS found almost no signal when, iPhone 4 played a role in the metal frame, making it the normal call. So, iPhone 4 signal problems do exist, but not serious.

I have the same opinion by means of you that iphone4 is superior in case of network from iphone3G and Nexus the iphone4 is capable to make a normal call in excessive conditions at the same time as iphone 3G and Nexus are in addition not bad additional than in comparison to other in making call iphone 4 is the best.
