Thanks to Mike Traugott, there is some more recent CDC data for the US.
Among the findings from the first 6 months of 2006, approximately 10.5
percent of households do not have a traditional landline telephone, but
do have at least one wireless telephone. Approximately 9.6 percent of
all adults-21 million adults-live in households with only wireless
telephones; 8.6 percent of all children-more than 6 million
children-live in households with only wireless telephones.
Two percent of households do not have any telephone service (wireless or
landline). Approximately 4 million adults (1.8 percent) and 1.4 million
children (1.9 percent) live in these households.
The results also reveal that:
Nearly one-half of all adults living with unrelated roommates live in
households with only wireless telephones (44.2 percent). This is the
highest prevalence rate among the population subgroups examined.
Adults renting their home (22.5 percent) are more likely than adults
owning their home (5.1 percent) to be living in households with only
wireless telephones.
Among adults less than 25 years of age, more than 6 million live in
households with only wireless telephones. Nearly one in four adults aged
18-24 years live in households with only wireless telephones (22.6
percent).
The prevalence rate decreases as age increases: 12.5 percent for adults
aged 25-44 years; 5.3 percent for adults aged 45-64 years; and 1.3
percent for adults aged 65 years or over.
Men (10.7 percent) are more likely than women (8.5 percent) to be living
in households with only wireless telephones.
Adults living in poverty (15.8 percent) are more likely than higher
income adults to be living in households with only wireless telephones.
Adults living in the South (11.4 percent) are more likely than adults
living in the Northeast (7.2 percent), Midwest (10.2 percent), or West
(7.8 percent) to be living in households with only wireless telephones.
Most major survey research organizations, including NCHS, do not include
wireless telephone numbers when conducting random-digit-dial telephone
surveys. Therefore, the inability to reach households with only wireless
telephones (or with no telephone service) has potential implications for
results from health surveys, political polls, and other research
conducted using random-digit-dial telephone surveys.

Estimates
Some public survey data I found showed that 8% of British homes had a
mobile but no fixed line; and suggested that lone parents were most
likely to have given up their fixed line phones in place of mobiles.
The main problem in the UK for using fixed line phones for sampling is
that about half of households are now "ex-directory": see

Subject: Telephone Coverage and Health Survey Estimates
Hello all,
Here is an article from the Center for Disease Control (of all places).
They are interested to know if the shift form landline to wireless
telephony biases their surveys. They do what seems to be a good job of
reporting on the adoption rates for mobile telephony.
The results and conclusions are as follows:
Results. When interviewed, 7.2% of adults, including those who did and
did not have wireless telephones, did not have landline telephones.
Relative to adults with landline telephones, adults without landline
telephones had greater odds of smoking and being uninsured, and they had
lower odds of having diabetes, having a usual place for medical care,
and having received an influenza vaccination in the past year.
Conclusions. As people substitute wireless telephones for landline
telephones, the percentage of adults without landline telephones has
increased significantly but is still low, which minimizes the bias
resulting from their exclusion from telephone surveys. Bias greater than
1 percentage point is expected only for estimates of health insurance,
smoking, binge drinking, having a usual place for care, and receiving an
influenza vaccination.
