[Q] Omate TrueSmart change baseband freq ?

[Viperdk81]

Hallo, I bouth by mistake a 1900mhz TrueSmart and cant use 3g here in EU, so I was thinking maybe I can change the baseband freq to 2100mhz. I did abit of research and it seems that the MT6572/MT6166 is capable of running in both the 1900mhz and 2100mhz 3G-FDD baseband freq, but is it controlled by the firmware or does it use different pin's on the SoC, and if so can I rewire the pin's and the use the 2100mhz firmware ?
Hope someone can help me with this, thanks

I'm also interested in the different models. Installing ROMs with the other baseband used to brick devices back in the bad old days of Windows Mobile, has that changed?

Rewiring is a definite no-go. The SOCs are a BGA package I think, meaning hundreds of solder balls under the chip where you can't see them.

Changing basebands has been done, the first US devices had EU antennas.
The result was not so good, the antennas are tuned for 1900/2100.
But 2G-EDGE is not so bad for the apps usable in the TS.
However, especially city coverage and some operators, are 3G only...
