Shorter version of the long story: http://tabletroms.com/forums/showthread.php?510-Success!-3G-USB-modems-now-w...
There is a statically compiled ARM version of usb_modeswitch available on http://draisberghof.de
Thanks for the pointer. Will try to get it to work with Tablet and USB modem that I have.
Regarding first project (Bluetooth DUN), aim is similar. Aim is to access net via cell phone and share that with Tablet using Bluetooth.
