    Some of the readings in above snapshots are away from being real, are those snapshots taken from real network if so i do beleive that the field test is un true, for example there is no such as AFRCN 138 in GSM system, C1,& C2 cannot have the values of -32768, incase of DTx is off the rxqual sub and full should have the same values where its not!

    Not only that, but the graphics are all now wrong, since the field test screens changed with the 2.0 firmware update.

    Nut case–this hasn’t worked since the old 3.12 firmware. You must be stuck in some bad trip 4.1 you smoking some bad stuff!
