Exhibit 31.2
CERTIFICATION
 
 
I, John J. Stephens, certify that:
 
1.
 
I have reviewed this report on Form 10-Q of AT&T
 
Inc.;
 
2.
 
Based on my knowledge, this report does not contain
 
any untrue statement of a material fact or omit to state a material
fact necessary to make the statements made, in light of
 
the circumstances under which such statements were made, not
misleading with respect to the period covered by this report;
 
 
3.
 
Based on my knowledge, the financial statements, and
 
other financial information included in this report, fairly
 
present
in all material respects the financial condition, results of
 
operations and cash flows of the registrant as of, and for,
 
the
periods presented in this report;
 
 
4.
 
The registrant’s other certifying
 
officer(s) and I are responsible for establishing and
 
maintaining disclosure controls and
procedures (as defined in Exchange Act Rules 13a-15(e) and
 
15d-15(e)) and internal control over financial reporting
 
(as
defined in Exchange Act Rules 13a-15(f) and 15d-15(f))
 
for the registrant and have:
a)
 
Designed such disclosure controls and procedures, or caused such
 
disclosure controls and procedures to be designed
under our supervision, to ensure that material information
 
relating to the registrant, including its consolidated
subsidiaries, is made known to us by others within those entities,
 
particularly during the period in which this report is
being prepared;
 
b)
 
Designed such internal control over financial reporting,
 
or caused such internal control over financial reporting
 
to be
designed under our supervision, to provide reasonable
 
assurance regarding the reliability of financial reporting and the
preparation of financial statements for external purposes in
 
accordance with generally accepted accounting principles;
c)
 
Evaluated the effectiveness of the registrant’s
 
disclosure controls and procedures and presented in this report
 
our
conclusions about the effectiveness of the disclosure
 
controls and procedures, as of the end of the period covered
 
by this
report based on such evaluation; and
d)
 
Disclosed in this report any change in the registrant’s
 
internal control over financial reporting that occurred during
 
the
registrant’s most recent
 
fiscal quarter (the registrant’s
 
fourth fiscal quarter in the case of an annual report) that has
materially affected, or is reasonably likely
 
to materially affect, the registrant’s
 
internal control over financial reporting;
and
 
5.
 
The registrant’s other certifying
 
officer(s) and I have disclosed, based on our most
 
recent evaluation of internal control
over financial reporting, to the registrant’s
 
auditors and the audit committee of the registrant’s
 
board of directors (or
persons performing the equivalent functions):
 
a)
 
All significant deficiencies and material weaknesses in the
 
design or operation of internal control over financial reporting
which are reasonably likely to adversely affect the
 
registrant’s ability to record,
 
process, summarize and report financial
information; and
b)
 
Any fraud, whether or not material, that involves management
 
or other employees who have a significant role in the
registrant’s internal control
 
over financial reporting.
