Hello guys.
I recently flashed my nokia n9 with DFL61_HARMATTAN_40.2012.21-3.280.04.1_PR_LEGACY_280_ARM_RM-696_PRD_signed.bin

Everything is working fine except that I can't manually change the network mode between 3G DUAL and 2G modes. I tried to use the apps 2g/3g, network toggle, profilematic but neither seems to change the mode. It is always stuck in 3G and only switches to 2G when I am in an area with no 3G.

When I go to settings-mobile network-network mode, i cant even the 3g-dual-2g changine interface. It is always on Dual mode.....Please help
