Blackberry interference

I have a Blackberry 8700C--Cingular service, which I like pretty much, except for a few things. When I am on a land line and the Blackberry is receiving data there is an annoying buzz on the land line. This is independent of the phone I am on. Is this a problem with my unit or a feature of all similar devices?

In my experience, all GSM phones do this to some degree.

In my experience, I've seen this on all TDMA and GSM phones/devices running
on bands around 900Mhz (850/900) (Have also seen this on
analog phones)

I do not know if you will see the same on 1800/1900 bands, but changces
are there.

I have not noticed this with my CDMA devices.

Most cellphones do this, but most only when they are making a phone call. Because the Blackberry is in constant contact with the Blackberry servers you'll hear it more often.

I use Goodlink on my Treo, so this might account for the reason that the interference occurs often for me as well...

Comes with the territory. If you wrap your 'berry in aluminum foil that might solve the problem.

I think the copper mesh (the one used as RF shield) would work better.

(Side effect: no signal on your phone/PDA)

You'll find that CDMA phones don't do this to any real degree. TDMA phones, which includes GSM phones (Cingular, AT&T, T-Mobile...) do do this, sometimes really badly.
