You need to add 125 and 250 Mhz to the avoid_frequencies. @bigswed: are you sure that it really uses 125MHz? the telephone apps sets the "official" minimum to 125Mhz but the actual limits is determined by avoid_frequencies. All of those ugly workarounds for the minimum and 600Mhz are due to bugs in the closed-source Nokia Telephone app. If we had access to its source we could make it much simpler...
