I did post somewhere around here what I'd found when I tested the 9900 reception on WiFi and Mobile, with and without a case, but in a nutshell, using my case gave me between -6 and -8db better gain on both radios than without (assuming the BB is in your hand). That's not a ton of gain - but enough in many cases to enhance reception to a point where you'd say reception is fine.
