i heard a few people where have downgrade issues wm6 to wm5. i had wm6 then put wm5 back on with radio not being affected. what carrier do u have and wat radio version do u have? try installing the 1.41 radio rom then going back to wm5.
i know that im on my second 6700 cause the radio in mine burnt out somehow. i would have to take the battery out for 10 mins then put it back in for the radio to work, and it sounds like urs is the same. dont worry if it is cause that type of problem is covered un manufacturers warrenty even if u dont have insurance on it. as long as it hasnt been a year i think. not sure bout the year thing. they will say they will send u a new one for free, but if they find it was broken cause of sothin u did they will charge ya. they say "ok thats 500$ or we send ur old phone back if we find u broke it" but with a radio frying out there is no way the owner could be held responsible.
but like i said try runng the radio rom update and see if that fixes it. wm6 will NOT affect ur phone calls.
also they have the carrier authorized roms at utstarcoms page. its called the 2.x fix i think its 40mbs

also u might be able to get a 6800 when u trade in cause all the carriers are running outa 6700s. check to see, u might need to wait.
