Mobile Phone Signal Boosters

Airwave doesn't look too bad, another $15/mo - you may also look to see what your phone can support if you get a wireless (802.11x) card.  A friend got a blackberry with free VoIP calling, not sure if this is part of the data plan now or not.
Also, if there is any place in the house that gets reception, you may try keeping it in that one spot and using a bluetooth headset to wander.  I have a plantronics set that lets me get about 50 feet away before I get static.
