Comment How does a bumper help the 3GS? (Score 4, Insightful) 917
When he gave his theory why the iPhone4 drops more calls than the 3GS he says its because people already had bumpers. How does a bumper help reception on the 3GS? The 3GS's antenna isn't external, so you can't touch it. Having a bumper or not wouldn't make any difference at all.
Lame theory Steve.
