Depends on the frequency with EDGE/GSM. 850 is pretty bad. 1900 can have buzz but it is nowhere near as bad as 850. 850 devices can cause interference typically around 6 feet or so. My 1900 devices have to literally be on top of a speaker to cause buzzing.
Can't speak for 3G as my 8310 is the newest BB that I have.
