Welcome to TmoNews!!!
i do not have the problem on both of my nexus's. it works fine with me i do not drop 3g for any unknown reasons. my 3g is fine as long as i have coverage. tmobiles map says i should have perfect 3g. i have had crap 3g on 8 g1's, 5 cliq's, 1 mytouch, and now 2 nexus one's. so i personally think its tmobiles coverage, not the phone. you can show me a video of this and that but IMO its tmobiles coverage, im not saying this directly to anyone im saying this just to share my thoughts.
