I bought the 3gs on the day it came out. I bought the original iphone back in the day and the 3g when it came out. I remember that when the 3g came out dropped calls were very bad. And the 3gs is having the same problems. I am not really dropping calls but just always going to egde when i should have full 3g and saying "no signal" I put 3.1 on when it came out and i can not see a change even with the baseband and modem changing. anyone else having the same problems?
