                                EXPLANATORY NOTE


     This Registration  Statement as originally filed related to the offering of
9,662,736 shares of FON Common Stock of Sprint Corporation  ("Sprint")  issuable
under the Sprint Retirement  Savings Plan and the Sprint Retirement Savings Plan
for  Bargaining  Unit  Employees.  In  connection  with  the  merger  of  Nextel
Communications, Inc. with and into a subsidiary of Sprint in August 2005, Sprint
amended  its  Articles  of  Incorporation  to change  its name to Sprint  Nextel
Corporation  ("Sprint Nextel") and to redesignate its FON Common Stock as Common
Stock. No shares of Common Stock  registered under this  Registration  Statement
have been issued.

     The Sprint  Retirement  Savings Plan was amended effective January 1, 2006.
Common Stock is no longer  offered as an investment  alternative  for additional
contributions  or  exchanges  and the company  match is no longer made in Common
Stock.  Following the spin-off of Embarq  Corporation in May 2006, Sprint Nextel
is no longer the sponsor of the Sprint  Retirement  Savings Plan for  Bargaining
Unit Employees. Consequently, no additional shares of Sprint Nextel Common Stock
will be issued by Sprint Nextel under either Plan.  Accordingly,  the purpose of
this  Post-Effective  Amendment  No.  1 to  the  Registration  Statement  is  to
deregister  the  9,662,736  shares of Sprint Nextel Common Stock covered by this
Registration Statement.
