I do remember those threads but the conclusions are not determinant, that is why ppl keep trying it. See the right side, it is good 4 every1 know about the real issue on it.

Had the feeling that the hardware supports it just because of "regulations,strategy,etc" it is just limited to the bands released.

If there is a way of course I will use it here for Perú 850-3G. Hack, trick,Swap chip, SW tunning up, etc. that could be useful for many.

So, what cellphone component or linux package/library/BIOS controls the BANDS ?
