No antenna problems with and without case.  One zoom problem that has been  adjusted. Other than that none! 
   
Had a 3GS and this phone is so much better.
I love the screen and it's pretty fast. I am a heavy phone user and no problem with the reception and the sensor.
I am onto photography but I am leaving today for North Va and Washington DC and decided to leave my good camera home and just use my phone. I'll report on reception issues, if any from there.
I love the IP4!!!
