So I recently purchased a new house and the area where I now live, ATT service is kinda weak in the house. On a good day and in certain places I hovered around 2 bars. So I picked up my new iPhone 4 and noticed the MicroCell was released in our area. I picked one of those up also and hooked it up (praying to cure my weak reception woes). Sure enough, I went from 1 - 2 bars to FULL bars and Not A Dropped Call since. PLUS, all my calls made from the house are free (don't go against my minutes). So the wife and I are thrilled that this thing ACTUAL WORKED (ATT, go figure). So those with reception woes (outside of the bumper fix issues) but with real reception woes due to weak reception areas, try a Microcell. It worked GREAT for me. It's only $50 for the unit.
