                                EXPLANATORY NOTE


     This Registration  Statement as originally filed related to the offering of
250,000  shares of Common Stock ("Sprint  Common  Stock") of Sprint  Corporation
("Sprint") issuable under the Centel Retirement Savings Plan for Bargaining Unit
Employees.  128,535 shares were issued by Sprint before the  reclassification of
Sprint Common Stock into FON Common Stock and PCS Common Stock in November 1998,
leaving  121,465 shares.  The remaining  121,465 shares were  reclassified  into
121,465  shares of FON Common Stock and 60,732  shares of PCS Common  stock.  No
shares of FON Common Stock were issued before the  two-for-one  split of the FON
Common  Stock in the 1999 second  quarter,  leaving  all  121,465  shares of FON
Common Stock. The two-for-one split of the FON Common Stock increased the number
of shares of FON Common Stock under the registration statement to 242,930 shares
of FON Common  Stock.  No shares of PCS  Common  Stock  were  issued  before the
two-for-one  split of the PCS Common  Stock in the 2000 first  quarter,  leaving
60,732 shares of PCS Common Stock. The two-for-one split of the PCS Common Stock
increased  the  number of  shares of PCS  Common  Stock  under the  Registration
Statement to 121,464 shares of PCS Common Stock.

     Following  the  recombination  of the PCS  Common  Stock and the FON Common
Stock in April 2004, the remaining shares of PCS Common Stock were deregistered.
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 and to redesignate
its FON Common Stock as Common Stock.

     No additional shares of Sprint Nextel Common Stock will be issued under the
Plan.  Accordingly,  the purpose of this  Post-Effective  Amendment No. 3 to the
Registration  Statement is to deregister the remaining  242,930 shares of Sprint
Nextel Common Stock covered by this Registration Statement.
