        This Amendment No. 2 supplements and amends, with respect to AT&T
Wireless Services, Inc. ("AT&T Wireless"), JVII and MMM Holdings, Inc. ("MMM
Holdings"), the Schedule 13D originally filed with the Securities and Exchange
Commission by JVII, AT&T Canada Investments Inc. ("AT&T Investments"), BT
(Netherlands) 1 B.V. ("BT Investments") on behalf of and for the account of BT
Longmont (Luxembourg) IV SARL, AT&T Corp ("AT&T") and British Telecommunications
plc ("BT") on August 27, 1999 (the "Original Filing"). This amendment is being
filed to reflect the split-off of AT&T Wireless from AT&T on July 9, 2001, as a
result of which AT&T Wireless became an independent, publicly traded company,
and the acquisition by MMM Holdings of BT Investments' interest in JVII, which
occurred on July 3, 2001.

(formerly Rogers Cantel Mobile Communications Inc.) (the "Issuer").

        The name of the Issuer and the address of its principal executive
offices are:

Original Filing is hereby amended as follows:

of AT&T Wireless from AT&T referred to below, pursuant to a separate Partnership
Transfer Agreement, dated as of December 29, 2000, between AT&T Investments and
AT&T Wireless (the "AT&T Wireless Partnership Transfer Agreement"), AT&T
Wireless purchased all of AT&T Investments' interest in JVII.

        On July 9, 2001, AT&T Wireless split-off from AT&T and became a separate
public company that owns and operates all of the businesses that constituted the
AT&T Wireless Group before the split-off. Prior to July 9, 2001, AT&T Wireless
was a wholly owned subsidiary of AT&T.

        The following supplements information contained in Item 2 of the
Original Filing and provides information concerning the name, business address

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

        The information contained in Item 3 of the Original Filing is hereby
amended as follows:

        Pursuant to the MMM Holdings Partnership Transfer Agreement, the
aggregate purchase price of the interest in JVII purchased by MMM Holdings from
BT Investments was US$380,229,966. The funds used by MMM Holdings in such
purchase were from working capital of AT&T, and none of the consideration for
such purchased interest was represented by borrowed funds.

        Pursuant to the AT&T Wireless Partnership Transfer Agreement, the
aggregate purchase price of the interest in JVII purchased by AT&T Wireless from
AT&T Investments was US$359,720,179, which amount is payable pursuant to the
terms of a Term Sheet for Loan Agreement, dated as of December 29, 2000, between
AT&T Wireless and AT&T Investments.

        On April 23, 2001, pursuant to a rights offering of the Issuer, JVII
acquired an additional 7,459,789 Class B Restricted Voting Shares for an
aggregate purchase price of US$106,210,166.87. The funds used by JVII in such
purchase were from working capital of AT&T Wireless, and none of the
consideration for such purchased interest was represented by borrowed funds.

ITEM 4. PURPOSE OF TRANSACTION.

        The information contained in Item 4 of the Original Filing is hereby
amended as follows:

        The purpose of the transactions described in Item 3 above is to allow
AT&T Wireless and the Issuer, two of North America's largest providers of
wireless services, to offer customers throughout Canada wireless services under
the Rogers AT&T Wireless name. Such arrangement increases AT&T Wireless's built
network North American population coverage by 28 million.

        (a)-(j) Pursuant to MMM Holdings' buyout of BT Investments' interest in
JVII, Alfred Mockett and Sohail Qadri, BT's representatives on the Issuer's
Board of Directors, have resigned and, to date, have not yet been replaced.
Under the Shareholders Agreement referred to below, JVII has the right to
designate two directors to fill such vacancies.

        On June 14, 2001, the Issuer, Rogers Communications Inc. ("Rogers
Communications"), the majority shareholder of the Issuer, and JVII amended the
Shareholders Agreement (as defined and described in the Original Filing) (the
"Shareholders Agreement") to institute certain governance rules as a condition
of Industry Canada's(1) agreeing to issue certain spectrum licenses to Rogers
Wireless Inc. ("Rogers Wireless"). Such amendment to the Shareholders Agreement
generally requires that no meeting of the Board of Directors of the Issuer or
Rogers Wireless or the executive committee of such Boards of Directors will be
conducted unless a majority of the directors present at such meeting are
resident Canadians (as defined in the Canada Business Corporations Act), and at
least 50% of the directors present at such meeting are Independent Directors (as
defined in such amendment to the Shareholders Agreement).

        On June 12, 2001, Rogers Communications, the majority shareholder of the
Issuer, announced that it is proposing to acquire all of the outstanding Class B
Restricted Voting Shares of the Issuer owned by the public (other than JVII and
Rogers Communications) in consideration for 1.1 Class B Non-voting Shares of
Rogers Communications for each of the Issuer's Class B Restricted Voting Shares
held. The transaction is proposed to be carried out as a merger of the Issuer
and Rogers Wireless Communications Inc., a newly incorporated subsidiary of
Rogers Communications. An Independent Committee of directors of the Issuer was
constituted to review the proposed transaction. The Independent Committee
retained RBC Dominion Securities Inc. ("RBC DS") as its financial advisor in
connection with the transaction and to prepare an independent valuation of the
Issuer's Class B Restricted Voting Shares. RBC DS concluded in its valuation
that the fair market value of the Issuer's Class B Restricted Voting Shares is
in the range of CDN$31.00 to CDN$36.00 per share. In addition, RBC DS concluded
that the transaction is inadequate from a financial point of view to the
minority shareholders of the Issuer. The Board of Directors of the Issuer (with
all directors abstaining, other than the members of the Independent Committee)
has recommended that shareholders of the Issuer vote against the proposed
transaction at a meeting of the shareholders to be held on September 11, 2001.

        Pursuant to the Shareholders Agreement, JVII has an obligation to
support and not oppose a transaction of this type if certain conditions relating
to JVII's governance rights, liquidity and access to information are met. In
connection with this transaction, JVII, Rogers Communications and the Issuer are
currently negotiating amendments to the Shareholder Agreement that relate to
liquidity, governance and information rights. JVII currently expects to come to
terms with the Issuer and Rogers Communications relating to these rights.

        Completion of the transaction is subject to certain conditions,
including, for example, no material adverse change in the business of the
Issuer; shareholders holding not more than 150,000 of the outstanding Restricted
Voting Shares of the Issuer shall have exercised their dissent rights under
applicable law; and receipt of approvals of shareholders of the Issuer,
including the approval by a majority of the votes cast by minority shareholders
(other than JVII and Rogers Communications) of the proposed transaction and the
waiver of certain provisions of the Minority Shareholder Protection Agreement,
dated August 7, 1991, between Rogers Communications and the Issuer.
