I flashed this radio last week. For me at least, this radio has given me about 2-5 dbm improvement in reception. I've flashed quite a few of the radios from MR2- MR4, and now this radio. Every time i do i make sure i'm at the same place in my house as a point of reference. All the other radios have been really close in data performance and call quality. This one however, seems to be just a little better in all aspects. But, from all the different threads and countless comments in all the forums about radios. I'm convinced that radio performance varies greatly from different areas, different phones, ROMS, and different people. Even though this radio kicks @!! for me it might suck for the next guy.
