I know that I do.  I found a good review on CrunchGear.com about  a small repeater that will give your better signal strength indoors.   At 169.00 dollas, it is by no means cheap, but if you are on the phone all the time, it could be a lifesaver.  I do a lot of business calls from my house so I will be getting one!

Here is an excerpt from the review:

“The YX300 is about four inches long and has a plastic antenna and power cable. You stick the antenna to your window using the included suction cups and plug in the device. When the light is green, your cellular reception is clean. If it’s red then the box is too close to the antenna and you simply have to move it away. In my new house I’ve found that my calls are cutting in and out. After installing the YX300, I anecdotally notice less cut-outs and I noticed more bars and a higher signal strength as compared to the situation without the YX300. For example, I just plugged in the YX300 and now have full reception at -85 dBm on a T-Mobile Sidekick LX. I unplugged the zBoost and it immediately began dropping to -91 dBm. Plugging it back in got me -83 dBm.”
