Amendment No. 3

    This amendment is being filed to include material that was redacted in
earlier filings.

Item 4.   Change in Registrant's Certifying Accountant

    On April 6, 2001, BDO Seidman, LLP ("BDO Seidman"), Ultradata's
principal independent accountant, resigned from its engagement to audit
Ultradata's financial statements for the year ended December 31, 2000.

    The report of BDO Seidman on Ultradata's financial statements for the
year ended December 31, 1999 did not contain an adverse opinion or a
disclaimer of opinion, and was not qualified or modified as to uncertainty,
audit scope, or accounting principles.

    Ultradata and BDO Seidman have not, in connection with the audits of
Ultradata's financial statements for the years ended December 31, 2000 or
December 31, 1999, had any disagreement on any matter of accounting principles
or practices, financial statement disclosure, or auditing scope or procedure,
which disagreement, if not resolved to BDO Seidman's satisfaction, would have
caused BDO Seidman to make reference to the subject matter of the disagreement
in connection with its reports.

    Advice regarding management during 2000 audit
    ---------------------------------------------

    During the audit of Ultradata's financial statements for the year 2000,
BDO Seidman informed the Audit Committee of Ultradata's Board of Directors
that information had come to its attention which it believed indicated that
members of Ultradata's management, including its Chief Executive Officer, had
attempted to mislead one of Ultradata's customers.  Based on that information,
BDO Seidman orally advised the Audit Committee that it was unwilling to rely
on the representations of Ultradata's Chief Executive Officer.

    On April 5, 2001, Ultradata's Board of Directors met to review the
evidence regarding the conduct of its Chief Executive Officer and to consider
BDO Seidman's statement that it could not rely on the Chief Executive
Officer's representations.  As a result of that review, the Board of Directors
adopted a number of internal controls procedures, including the preparation of
a code of business ethics, the appointment of an ombudsman to facilitate
implementation of the code of business ethics, and the separation of the
office of Chief Executive Officer from the office of President.  The Board
determined, however, that further remedial action was not warranted by the
facts presented, having concluded (1) that there has never been an allegation
of wrongdoing by the Chief Executive Officer other than this one event; (2)
that the type of conduct in which the Chief Executive Officer engaged was not
uncommon in wholesale marketing, and (3) that the customer which was the
subject of this event had been fully informed of the relevant facts in writing
on two occasions and had stated its intent to remain a customer of Ultradata.
On April 6, 2001, Ultradata reported to BDO Seidman the actions taken by the
Board of Directors, and BDO Seidman resigned from its engagement.

    Advice regarding likelihood of a modification of opinion on 2000 financials
    ---------------------------------------------------------------------------

    On February 9, 2001, BDO Seidman orally advised the Audit Committee that
it would require Ultradata's management to make representations that would
support a determination that Ultradata is able to continue as a going concern.
Because BDO Seidman subsequently determined that it was unwilling to rely on
management's representations, there was no determination made as to
Ultradata's ability to continue as a going concern.  At no time did BDO
Seidman advise the Audit Committee that it was likely to modify its opinion to
reflect substantial doubt as to Ultradata's ability to continue as a going
concern.

    Advice regarding internal controls during 1999 audit
    ----------------------------------------------------

    In a report to the Board of Directors dated April 29, 2000, BDO Seidman
advised the Board that Ultradata personnel had not received sufficient
training regarding accounting issues or SEC reporting, as a result of which
said personnel were unable to provide the information necessary to adequately
determine the proper accounting on a timely basis.  In response to this advice
and after further discussion with BDO Seidman, Ultradata retained a consultant
to assist in preparation of its reports to the SEC.

    In the same report dated April 29, 2000, BDO Seidman advised the Board
that Ultradata did not perform certain quarter-end and year-end closing
procedures necessary to insure the accuracy of its general ledger, including
the coordination of the receipt of audited financial statements from
Ultradata's significant equity investees.  In response to this advice,
Ultradata's one remaining significant equity investee has accelerated the
preparation of its audited financial statements.

    Advice regarding internal controls during review of March, 2000 quarterly
    -------------------------------------------------------------------------
     report
     ------

    In a letter to the Audit Committee of Ultradata's Board of Directors
dated July 31, 2000, BDO Seidman advised that Ultradata's procedures in the
first quarter of 2000 with respect to incorporation of financial information
from a significant equity investee into Ultradata's quarterly report had been
inadequate.  In response to this advice, Ultradata filed an amendment to the
quarterly report.

    Ultradata has authorized BDO Seidman to respond fully to inquiries from
the successor accountant concerning the subject matter discussed in this
report.

    On April 12, 2001, Ultradata retained the firm of Weinberg & Company,
P.A., C.P.A. to audit Ultradata's financial statements for the year ended
December 31, 2000.  At no time during the past two fiscal years or any
subsequent period did Ultradata consult with Weinberg & Company, P.A., C.P.A.
regarding either the application of accounting principles to a specified
transaction or the type of audit opinion which might be rendered on
Ultradata's financial statements or any matter of the sort described above
with reference to BDO Seidman.


Item 5.   Changes in Board of Directors and Audit Committee.

    On April 6, 2001, John J. Clancy and Steven H. Akre resigned from
Ultradata's Board of Directors.  The resignations were reported in a press
release issued on April 13, 2001.  Subsequently, H. Krollfeifer, Jr., an
independent member of Ultradata's Board of Directors, was elected to join
Donald E. Rattner on the Audit Committee of the Board of Directors.  Mr.
Rattner will serve as Chairman of the Audit Committee.

Exhibit 16


April 17, 2001

Securities and Exchange Commission
450 Fifth Street N.W.
Washington, DC 20549

Dear Sir or Madam:

We have been furnished with a copy of the response to Item 4 of Form 8-K for
the event that occurred on April 6, 2001 which has been filed April 13, 2001,
by our former client Ultradata Systems, Inc.  We agree with the statements
made in response to that item insofar as they relate to our firm, except as
follows:

We were advised by the Audit Committee of the results of an independent
counsel's investigation undertaken to determine the legality of actions by
management during a test marketing campaign through a major retailer's stores
and the legality of disclosure of the success of such test to one person under
the fair disclosure rules (Regulation FD) for SEC reporting companies.  The
Audit Committee developed a series of recommended actions to be voted upon at
the April 5, 2001 Board meeting.  Upon learning of the Board's decision to
reject the Committee's recommendations regarding a management member, we
notified the Company and the Audit Committee of our resignation on April 6,
2001, indicating that we had determined we could no longer rely upon
management representations.

We had previously advised the Audit Committee that had we been able to issue
our report on the annual financial statements for the year ended December 31,
2000, that opinion would have likely been modified to reflect substantial
doubt as to the registrant's ability to continue as a going concern.

          Very truly yours,


          /s/ BDO Seidman, LLP
