Our town voted against another cell tower, so I never really had great coverage in my house.
When ZDNet gave the new Zboost wireless extender an awesome review, I went out and got one.
It works great. My ATT iPhone went from 0-1 bars to 2-3 bars.
Great product!
Check it out at www.wi-ex.com or buy it at Amazon.
By the way, South Beach also has more bars in more places...
