so I previously had an evo that I ended up getting rid of for two reasons. battery life and very poor wifi reception. I went back to an iphone 3gs and then iphone 4 ( I am not a fanboy) so now I have decided to go back to android just to give it a shot. while I see the battery is better, the wifi signal is still abysmal for me. either iphone always had 4 to 5 bars, the evo and now the vibrant, one to two max. anything I am missing in terms of settings to get better wifi?
