I have a
signal booster for my home, but for coverage all over, in every room!
I purchased it from i think it was
Unwiredsignal.com... I'll make sure... Yup it is... wasn't cheap though, but of course you get what you pay for. Definately worth it. I just noticed they have a C-Booster for the blackberry curve... if thats of any help to any one else...
They have a lot of ways to boost your current signal. Of course if you don't have atleast a weak signal it won't help.
You should
do your research on every brand there is out there to see which one you feel is right for you.
I did all my research and I found that the
Wilson Electronics was my best option.
On their site theres also a page where they compare brands of boosters... I think its
Wilson VS The Competition
Hope this helped.
