Ever since I have downloaded and installed this update my 3GS has a much weaker signal strength and I am having issues with it linking to my Sony car stereo which btw is Iphone compatible. Before the update I was getting a full signal bar pretty much everywhere. Now I am lucky to get 3 or 4 bars. I was just wondering if anyone else with a 3GS is getting this problem after the 4.0.1 update??? I guess I may be able to restore the origional settings. Has anyone ever restored their Iphone and if so does it wipe out everything or just certain updates???
