I have owned my bionic for almost a year, (in cell phone days it seems like a year) actually on my replacement certified one. I am in a spotty coverage area and have a range extender at my house. There are data issues when going from area to area and in and out of 3g 4g just got off phone with motorola and they admit to this. Are saying the 901 update did not address all radio concerns but are working on a 902 update which will help. did not have any information on expected release date. I do like the Bionic and hope they can fix the radio issue apparently enough people do have issues.
