HTC G2

Is anyone els haveing a problem like mine. When i hold the phone I loose signal if inside my house. My g1 gets great signal in my house but the g2 looses service when i hold it but if i sit it on my desk it works fine. If htc trying to copy apple? I love the phone its everything i wanted and more and the metal case is nice but im wondering if the case is whats causeing the reception problems.
