Well right back to where i started after patching to 4.0.1 and restoring my data. Never had a dropped/missed call in my house with my 3G S, always had full signal, closest tower is only quarter a mile away in line of sight. Now I'm lucky if I get 2 bars, most calls I receive go straight to VM, longest call I've been able to keep is 30 secs before call fails. 3G data is unusable. My iPad has full 3G signal and fast in the same location. This was on both my original 4 phone and the replacement today. Never had problems like this with previous iPhones from iPhone 1 on up through 3G S. A couple Blackberry's on AT&T always worked flawless same location. Wife's iPhone 4 is exhibiting the same problems as mine in her hands. Not sure how Steve can sight this as a perception problem, while in the Apple store replacing mine, 5 other people before and after me where all there for the same problem and all walked out with a replaced phone. Followed up with one of the others that was in line with me and hers is still doing the same thing as well.
