Its this phone. I have had a mytouch, a G1, and a Slide, and now a vibrant. (Yeah, I know, but I work for T-Mo!) The Vibrant and the Slide were the two worst receivers of the bunch, and the Vibrant is noticably worse. I hope a radio firmware update fixes it, but I doubt it. The old myTouch and G1 were champs when it came to signal strength. They would continuously hold on to more signal (roughly 2 bars more) than my girl's Curve.
