Anyone out there still having reception issues after fitting a case or bumper?
I bought a $25 Griffin case from BB (rubber around the sides, clear plastic on the back) and I don't have any reception issues at all now. The signal at my house is very weak. I couldn't hold a call with the iP4 without the case, and I was none too happy about it. However, it works at least as good as my 3G did now, if not better.
Apple bumper case fixed my issues, I planned to get one anyway so I am not too annoyed.
