The "GSM-buzz-noise" issue isn't related to image used. At least that's what
we think of it at the moment. It's a hw-issue. (Please note we fixed other
hw-issues by sw-patch - compare sd-card/GPS). Anyway there's no *bug* in any
of the sw-stacks/images that causes this issue, so changing image won't help,
until we eventually might find a sw-fix for the hw-issue.

There isn't any yet. My regret :.(

Only thing you may try for now is changing GSM-provider, as it seems to be
very clear the issue is to be found on some GSM-networks, and not (or less)
on some others. Generally the 1800/1900 networks seem to be more likely to
cause this problem than the 850/900 networks. For Germany I got reports f
noise only for E+ network (and resellers)

Hard to tell. We don't get sufficient number of reports, and due to nature of
reports nearly all are problem-reports, people without problems usually don't
post a report.

Investigation on issue continues.
