Anyone have a signal booster for their cell phone? If so does it really work?

Thinking about getting this signal booster, does anyone use one of these and if so does it help alot? I have a Nokia 8290 with Cingular Wireless (SF Bay Area)

I posted this same question like a week ago; judging from their replies, ugh...no You can look for the thread in OT from last week, as I am lazy and going to lunch right now.
