900 MHz UMTS-3G Band on Atrix HD???

[sasostef]

Hello!

Would it be possible to get the 3G-UMTS 900 MHz network on Atrix HD? My operator used 900 MHz frequency on 3G network. Atrix MB886, however, it only supports 850, 1700, 1900 and 2100 MHz. Chipset has the same as the Razr Maxx-HD, which supports the 900 frequency. What would happen if I flash his radio.img? Any idea how I could switch on 3 g network for faster data transfer?

Thanks for advice.

Have nobody in Europe this Phone? In EU is for UMTS-3G 900MHz frequency standard, as 2100Mhz too, But 900MHz has some advantages and several provider work only on 900 MHz. I know in Europe Motorola sales only RAZR HD, but Atrix HD has the same chipset as RAZR and maybe we can with Radiocomm or whit flashing radio.img or NON-HLOS.bin get RAZOR bands 850\900\1900\2100 on 3G Network?

Epinter make good ROM for both devices any maybe we can only change the right radio files, before flashing to get right bands.

Nobody try this?
