Not much but enough to drop a call > if I'm in a marginal area. Now, compare that to the iPhone 4 drop of > about 30dB. I have an old, cheap LG VX3400 on Verizon. In my living room cupping the antenna sticking out the top drops it from -94 dBm to -110 dBm, though the call still stays connected and is still decent quality. I wish I knew how to get that display with my GSM/UMTS Nokia 6700. I can get that one to drop an AT&T GSM call in my living room if I put my hand around the top third of the (candybar) phone.
