I haven't had a 3G signal for 3 weeks
I'm not going to lie. But most service companies be it cell phones or internet blame it on the thing they don't use. When I used to call about my internet being down, the ISP blamed it on the router and the router blamed it on the ISP. Its in essence their scapegoat. It may be both but more often than not it is the wireless company or ISP. This is just from my experience.
It does it everywhere, and I can compare it to my old LG "V" from 2005, and it doesn't do the same thing. Keeps a strong evdo/3g signal while my droid bounces in and out
