Boost HTC Diamond antenna/reception

Does anyone know of what to do in order to boost or get a better antenna reception with the HTC Diamond. I have one and there are certain open space places where the phone doesnot have reception and the batterry life decreases because the phone is looking for service. Also, does anyone know how to improve battery life? Thank you

keep a good charge and discharge habbit, and avoid too hot or too cold environment.

there are a few registry hacks on www.xda-developers.com that help with battery life and overall phone performance. take a look over there. there is a lot more info over there and more reputable people than what is on this site
