    That would only work *if* the Nokia handset in question has both bands and whether a Nokia flash could disable GSM 1800/1900. In most cases, Nokias don't have the hardware with the bands in question. I don't know how this would work with the new quads such as the 6270.

    Motorola definitely would work to some degree since T-Mobile would carry Motorola quads with the GSM 850 band disabled. That could be restored with a generic flash/flex.

    As a matter of fact, its not even a flash/flex. Its a seem edit. I removed 850 from my Motorola V551 to force my phone onto the 1900 band for better in-home coverage.

    It is an advanced process where you upload your phone's operating system to your computer through a USB cable, you make changes with a hex editor, then reload the OS to the phone. This is not recommended for a beginner as you can risk turning your phone into a paperweight.

    I tried seem editing the other day on my e770V so I could get the FEM menu activated. I let it be in the end since it was too difficult and I didn't want to screw up my phone.

    I think I'm going to really play with the V551 once I get my new phone. I think I'm just going to turn on unmapped bits one at a time and see what happens, and make an expanded seem map.

    Jay,

    when I look at my e770v through XVI32 or any other seem editor, I must admit that I haven't quite figured out the system for offsets. Offset refers to the left column (i.e. Offset 2B) and the bit I want to change is listed at the top (i.e. 44). Is that right?

    Possible through which criteria? The hardware must support both bands and the only handsets in question are quads. Rogers sold the Motorola V300 as a GSM 850/900/1900 model a few years back but other than that, I've never seen a handset that supports GSM 850/900 without being a quadband.
